MONOPOLY Roll 'em Building Phase & House Multipliers Explained: Boost Odds by Number (Real Data)
By LiveCasinoData editorial team · Updated 2026-08-28 · 14 min read
MONOPOLY Roll 'em has no separate bonus game; instead, a Building Phase places houses on random squares before every roll, each carrying a 1x to 300x multiplier that boosts the Specific Number bet if the dice land there. Across 2,444 rounds we tracked, 12.2% of rounds carried a boosted winning square, but Seven was boosted in zero of 415 rounds, a pattern strong enough to look like a deliberate exclusion rather than noise. The biggest paid multiplier so far is 200x, on 2, 3, 11 and 12.
Key takeaways
- Houses are placed on random squares before each roll (the Building Phase), each carrying its own 1x to 300x multiplier that only pays out if the dice total lands on that exact square.
- Across 2,444 tracked rounds, 12.2% (298 rounds) had a Building Phase boost on the winning number, but the rate by number ranged from 10.3% (on 2) to 19.1% (on 12).
- Seven was boosted in 0 of 415 observed rounds, which our data flags as a likely built-in exclusion rather than a coincidence, meaning a Seven bet pays a fixed 3:1 with no multiplier variance.
- The highest multiplier paid in our tracking so far is 200x, seen on 2, 3, 11 and 12; no round has yet hit the 300x design cap.
- This is a newly launched game (15 July 2026) that we only started tracking on 2026-08-27, so every per-number figure here comes from a single 23-hour window and will firm up as more data accumulates.
MONOPOLY Roll 'em does not have a bonus round in the traditional sense; there is no side wheel, no bingo balls, no board walk. Instead, every single round carries a Building Phase, where Evolution places houses on random squares of the 12-square board before the dice roll, and each house adds a multiplier of up to 300x to whichever Specific Number bet matches that square. This page covers how that mechanic works and what our tracker has recorded so far: 2,444 rounds logged between 2026-08-27 and 2026-08-28, the entire history we have on this newly tracked game. For the base rules, start with the MONOPOLY Roll 'em guide.
What is the Building Phase in MONOPOLY Roll 'em?
The Building Phase is the step between the close of betting and the dice roll where MONOPOLY houses are placed on randomly chosen squares around the board. Two dice are rolled from shakers, and their total, from 2 to 12 across 36 possible combinations, decides which of the 12 squares the top hat piece moves to. Bets can go on Low (totals 2-6), High (totals 8-12), Seven (total 7), or any of the 11 Specific Number spots from 2 through 12.
Before the dice are thrown, one or more squares receive a house, and each house carries its own multiplier, anywhere from 1x up to the 300x cap. If the dice total ends up matching a square that got a house, the Specific Number bet on that total pays the boosted amount rather than its base payout. The isBoosted field in our feed marks exactly this: a round where the winning square carried a house. Every house disappears at the end of the round; nothing carries forward, and the next Building Phase starts fresh.
Evolution has not published whether the same house multiplier also applies to the Low, High or Seven group bets, or only to the Specific Number spot on that square; our own collector only records the Specific Number payout in the multiplier field, so we cannot confirm that split from our data either. Treat that as an open question rather than a settled rule until the in-client help spells it out.
How often does a number get boosted by the Building Phase?
Overall, 12.2% of the 2,444 rounds we tracked had a Building Phase boost on the winning number, meaning roughly one round in eight paid more than the base Specific Number odds. That rate is not spread evenly across the 11 numbers.
| Number | Rounds observed | Boosted rounds | Boost rate |
|---|---|---|---|
| 2 | 78 | 8 | 10.3% |
| 3 | 113 | 18 | 15.9% |
| 4 | 177 | 21 | 11.9% |
| 5 | 274 | 37 | 13.5% |
| 6 | 367 | 50 | 13.6% |
| 7 | 415 | 0 | 0.0% |
| 8 | 324 | 51 | 15.7% |
| 9 | 291 | 45 | 15.5% |
| 10 | 190 | 30 | 15.8% |
| 11 | 147 | 25 | 17.0% |
| 12 | 68 | 13 | 19.1% |
Setting Seven aside, the boost rate for every other number sits between 10.3% and 19.1%, all plausible outcomes of the same underlying process given sample sizes of 68 to 415 rounds each. Nothing here suggests any number besides Seven is treated differently; the spread looks like ordinary sampling variation, not a pattern. We will revisit these numbers once more data accumulates, since a 23-hour window is not enough to pin down a stable per-number boost rate.
Why does Seven never get a Building Phase boost?
Seven paid its flat 4x payout in every one of the 415 rounds we observed it, with zero Building Phase boosts. That is the standout finding in our early data on this game.
If Seven were boosted at even the lowest rate seen among the other ten numbers (10.3%, on 2), we would expect roughly 43 boosted Seven rounds out of 415. Seeing exactly zero is not a plausible run of bad luck; it points to Seven being deliberately excluded from the Building Phase, most likely because a house landing on the seven square, the one every roll passes through most often (6 of 36 dice combinations, the highest of any total), would distort the game's payout structure too much if it could also carry a multiplier.
The practical effect: a Seven bet in MONOPOLY Roll 'em behaves like a fixed-odds wager. It pays 3:1 (4x total) and nothing else, every time it wins, with none of the round-to-round swings that a house boost introduces on every other number. That makes it a useful contrast against the Specific Number bets on 2 through 6 and 8 through 12, where the payout for a winning bet genuinely varies depending on whether a house landed on that square. The strategy guide covers how that fixed-versus-variable split affects bet selection.
What multipliers has the Building Phase actually paid?
The distinct paid multiplier values in our data so far are 4x, 5x, 6x, 8x, 10x, 12x, 15x, 20x, 25x, 30x, 40x, 50x, 80x, 100x, 150x and 200x. Some of those are unboosted base payouts (4x on Seven, 5x on 6 or 8, and so on); the rest reflect a house multiplier landing on the winning square.
Small numbers dominate. Rounds paying 50x or more made up 2.3% of our sample (55 of 2,444). Rounds paying 100x or more dropped to 0.8% (19 rounds), 150x or more to 0.4% (10 rounds), and 200x or more to 0.3% (8 rounds). No round in our tracking has yet paid anywhere near the 300x design cap; the biggest paid multiplier so far is 200x. That shape, a lot of small and mid-size results with rare large ones, is typical of a multiplier feature layered on top of fixed base odds, and it matches what other Evolution game shows with random per-round multipliers tend to look like once enough rounds accumulate.
What is the biggest multiplier recorded so far?
The largest paid multiplier in our 2,444-round sample is 200x, which has landed six times: twice on 2, once on 3, twice on 11 and three times on 12. A separate 150x result has landed twice, both on 10. No round has reached the theoretical 300x ceiling yet, which is not surprising given that our full history is only 23 hours of play.
Because the Building Phase multiplier applies on top of the base Specific Number odds, a 200x result on 12 pays far more than the same 200x would on a middle number, simply because 12's base odds (24:1) are already the richest on the board. We come back to why corner numbers behave this way below.
How much does a house boost change the Specific Number payout?
Every Specific Number spot has a fixed base payout that applies when no house lands on that square, and a maximum boosted payout that applies when the biggest possible house (300x multiplier) lands there.
| Number | Base payout | Base multiplier | Max boosted payout | Max boosted multiplier |
|---|---|---|---|---|
| 2 or 12 | 24:1 | 25x | 299:1 | 300x |
| 3 or 11 | 11:1 | 12x | 199:1 | 200x |
| 4 or 10 | 7:1 | 8x | 149:1 | 150x |
| 5 or 9 | 5:1 | 6x | 99:1 | 100x |
| 6 or 8 | 4:1 | 5x | 49:1 | 50x |
| 7 | 3:1 | 4x | not boosted | not boosted |
Two things stand out from this table. First, the gap between base and maximum boosted payout is proportionally largest on the corner numbers, 2 and 12, where the base 24:1 can theoretically become 299:1 if a full 300x house lands there. Second, Seven's row has no boosted column at all, since our data shows it never carries a house multiplier.
Why do corner numbers swing harder than middle numbers?
Corner numbers combine the lowest hit probability with the highest payout ceiling, which is the classic shape of a high-variance, low-frequency bet, the same structural pattern as a straight-up number in roulette or the rarest bonus segment on a money wheel game. In MONOPOLY Roll 'em, 2 and 12 each come up on only 1 of 36 dice combinations (2.78%), the rarest totals on the board, but they carry the richest base payout (24:1) and the highest multiplier cap (up to 299:1).
That structure shows up clearly in the average multiplier actually paid per number in our data, which folds boosted and unboosted rounds together: 2 averaged 31.79x and 12 averaged 37.43x, both far above the middle numbers, where 6 averaged 6.69x and 8 averaged 6.74x. Betting a corner number means fewer wins overall, since the number itself is rarer, but a noticeably larger payout on the wins that do land, both from the higher base odds and from a wider spread of possible boost outcomes.
The middle numbers (5, 6, 8, 9) sit at the other end: they hit more often (11% to 15% of rolls each) but their base payout tops out at 5:1 or 6:1 and their boost ceiling is capped lower (49:1 or 99:1), so both the typical and the maximum result are smaller in absolute terms. Neither shape is objectively better; they are different ways of distributing the same house edge across a session, and the RTP page works through what that means for expected return.
Does a Building Phase drought change the odds on the next roll?
No. Pooling all numbers together, our data shows an average of 8.2 rounds between any Building Phase boost landing on the winning square, with a longest observed gap of 53 rounds without a single boosted win anywhere on the board. Neither figure changes what happens on the next roll.
Each Building Phase is an independent event: houses are placed fresh, and the dice are thrown fresh, with no memory of what squares were boosted or hit in previous rounds. A 53-round gap without a boosted winner does not make the next round more likely to carry one, in the same way that a coin that has landed heads ten times in a row is still a 50/50 flip on the eleventh. We do not yet have enough rounds per individual number (68 to 415 each) to publish a reliable per-number gap statistic, so we are reporting the pooled figure only until the sample grows.
Treat any drought, on Seven's exclusion, on a specific number, or on the boost feature as a whole, as history rather than a signal. The dice have no memory, and neither does the house-placement system that runs the Building Phase.
How is the Building Phase different from Monopoly Live's bonus round?
MONOPOLY Roll 'em is one of four games in Evolution's Hasbro MONOPOLY license family, and the names get confused easily because they share art and branding, not mechanics.
Roll 'em is a dice game: two dice decide a total from 2 to 12, and the Building Phase places houses on the board before the roll to boost whichever Specific Number square the dice land on. Monopoly Live is a 54-segment money wheel where landing on a bonus segment sends the game into a separate 3D board walk, driven by dice rolls that move a token square by square. Monopoly Big Baller uses drawn bingo balls instead of a wheel or dice. Monopoly Roulette is a roulette wheel with added Monopoly-themed bonus pockets. If you came here looking for house and hotel multipliers on a 3D board walk rather than a dice total, that is Monopoly Live's bonus round, not this Building Phase.
Roll 'em's closest relatives in mechanical terms are actually other dice-based Evolution games rather than its Monopoly siblings; games like Lightning Dice and Super Sic Bo also pay out based on dice totals with random multipliers layered on top, even though neither carries the Building Phase name or the Hasbro license.
Do house multipliers apply to Low, High or Seven bets?
We do not know for certain, and neither, it seems, does most public documentation of this game. Secondary sources describe Low and High as paying roughly 2.5:1 down to 0.5:1 depending on how many numbers within the group have already been covered, and Seven as paying between 3:1 and 49:1, but our own collector only stores the Specific Number payout in its multiplier field, so we cannot verify from our data whether a house on, say, the 9 square also lifts a High bet that happens to include 9.
What we can say with confidence is what shows up directly in result_details.house_multipliers: every round logs every square that received a house that round, whether or not the dice landed there, alongside its multiplier value. That field is a record of the full Building Phase layout, not just the winning square, and it is the source of the boost-rate and payout figures throughout this page. Whether that same layout feeds into group bets is something we would rather flag as unconfirmed than guess at.
What's a common misconception about the Building Phase?
The most common one is assuming that seeing a large house multiplier appear on a square guarantees a big win. It does not. Houses are placed before the dice are thrown, entirely independent of the roll that follows; a 200x house can sit on the 4 square all round and pay nothing if the dice come up anywhere else. result_details.house_multipliers regularly shows large multipliers sitting on squares that never get touched, because the Building Phase and the dice roll are two separate random processes chained together, not one process where a visible house predicts the outcome.
A second misconception, given this is a brand-new game, is treating any of the per-number figures on this page as a settled long-run edge. MONOPOLY Roll 'em launched on 15 July 2026, and we only added it to our tracker on 2026-08-27, so everything above comes from a single 23-hour window of 2,444 rounds. Per-number sample sizes run from 68 rounds (on 12) to 415 (on 7), which is enough to notice a pattern as stark as Seven's zero boosts, but not enough to lock in exact boost rates or payout averages for every number. We will update this page as the sample grows past 90 days of history.
Where the numbers on this page come from
Board layout, bet types, base payouts, the 300x Building Phase cap and Evolution's headline 96.97% RTP figure are from Evolution's official game rules and press materials for MONOPOLY Roll 'em, launched 15 July 2026, cross-checked against CasinoScores' game guide. Observed boost rates, paid multipliers, gaps and record results are from the LiveCasinoData MONOPOLY Roll 'em tracker, covering all 2,444 rounds logged since we added the collector on 2026-08-27, as of 2026-08-28. Because this is both a newly launched game and a newly tracked one on our site, these figures will move noticeably as more rounds accumulate; the live page always reflects the current data, and the live stats page explains how to read every widget on it. For a wider view of how observed return compares with certified figures across every game we track, see the RTP monitor; for responsible-gambling tools including drought tracking, see the observatory. No bet on this or any casino game beats the house edge over time, and a long gap without a boost is not a reason to chase one; play only with money you can afford to lose.
Frequently asked questions
What is the Building Phase in MONOPOLY Roll 'em?
It is the step between betting close and the dice roll where MONOPOLY houses are placed on randomly selected squares of the 12-square board, each with its own multiplier from 1x to 300x. If the dice total lands on a square holding a house, the Specific Number bet on that total pays the boosted multiplier instead of its base payout. Houses reset every round.
How often does a number get boosted in MONOPOLY Roll 'em?
Across 2,444 rounds we tracked, 12.2% of rounds paid a boosted Specific Number multiplier. The rate varied by number, from 10.3% on 2 up to 19.1% on 12, with most numbers between 12% and 17%. Seven was the exception at 0% across 415 rounds. Sample sizes per number (68 to 415 rounds) are still small, so treat these rates as directional.
Why doesn't Seven ever get a house multiplier in MONOPOLY Roll 'em?
In our data, Seven paid its flat 4x (3:1) payout in all 415 observed rounds with zero Building Phase boosts, while every other number was boosted 10% to 19% of the time. That gap is too consistent to be chance at this sample size, so it looks like Seven is deliberately excluded from Building Phase boosts, making it the one fixed-payout bet on the table.
What is the biggest multiplier paid in MONOPOLY Roll 'em?
In our tracking so far the largest paid multiplier is 200x, which has landed six times: twice on 2, once on 3, twice on 11 and three times on 12. The design cap is 300x on a single square, which no round has reached yet. Rounds paying 100x or more made up 0.8% of our sample (19 of 2,444).
Is MONOPOLY Roll 'em the same as Monopoly Live?
No. Both are Evolution games under the Hasbro MONOPOLY license, but Roll 'em is a dice game where two dice totals (2-12) decide the winning number and houses boost that number's payout. Monopoly Live is a money wheel that sends a token around a 3D board on a bonus spin. The two share a theme, not a mechanic.
