Treasure Island Bonus Rounds Explained: John Silver's Loot, Billy Bones' Map, Ben's Lost Marbles & Captain Flint's Treasure

Treasure Island runs four separate bonus games off its 54-segment wheel: John Silver's Loot, Billy Bones' Map, Ben's Lost Marbles and Captain Flint's Treasure, covering 9 of the 54 spots between them. A fifth mechanic, the Top Slot, sits above the wheel and can multiply whatever segment lands next, number or bonus. This page covers the odds, the mechanics and what our tracker has logged across 211,021 rounds since Pragmatic Play's current version of the game went live. For the full rule set, see the Treasure Island guide or watch results arrive on the live tracker.

How many bonus segments does the Treasure Island wheel carry?

Nine of 54. Four segments trigger John Silver's Loot, two trigger Billy Bones' Map, two trigger Ben's Lost Marbles, and a single segment triggers Captain Flint's Treasure. The other 45 segments pay a straight number: 18 x "1", 15 x "2", 8 x "5" and 4 x "10", at 1:1, 2:1, 5:1 and 10:1.

That puts the combined bonus probability at 16.67% per spin, about one spin in six. Our last 90 days, 79,662 rounds, produced segment shares of John Silver's Loot 7.43%, Billy Bones' Map 3.76%, Ben's Lost Marbles 3.74% and Captain Flint's Treasure 1.87%, each within three hundredths of a point of the published counts. Across the full 211,021-round history the bonus rate sits at 16.72% (35,277 bonus rounds), and the last 30 days measured 16.76%.

Bonus	Segments	Theoretical odds	Observed share (90d)	Avg rounds between hits	Longest gap (90d)
John Silver's Loot	4 of 54	7.41%	7.43%	13.5	135
Billy Bones' Map	2 of 54	3.70%	3.76%	26.6	197
Ben's Lost Marbles	2 of 54	3.70%	3.74%	26.8	226
Captain Flint's Treasure	1 of 54	1.85%	1.87%	53.5	341
Any bonus	9 of 54	16.67%	16.76% (30d)	6.0	76

The wheel is doing what the segment count says it should. The gap columns matter more for reading the sections below than the share columns do: an "average gap" of 53.5 rounds for Captain Flint's Treasure is a long-run figure, and the game still produced a 341-round stretch without it inside a 90-day window.

How does John Silver's Loot work?

John Silver's Loot is a ball-draw bonus: balls are pulled one at a time, and a running multiplier climbs as the draw continues, ending either on a specific stop ball or after a fixed number of draws. Third-party sources disagree on the exact ball count and stop mechanic across the game's earlier and current versions, so treat the precise structure as directional rather than confirmed.

It is the most frequent of the four bonuses: 4 of 54 segments, 7.41% per spin, an average of one hit every 13.5 rounds in our 90-day sample, with the longest gap running to 135 rounds.

It is also the smallest payer. Across 5,918 hits in the last 90 days, the settled multiplier had a median of 7x, an average of 11.9x, a 90th percentile of 21x and a maximum of 1,000x. Read that as: half of all John Silver's Loot rounds paid 7x or less, and a four-figure result is a rare tail event, not a typical outcome.

How does Billy Bones' Map work?

Billy Bones' Map is a reveal game played on a grid or wall of hidden tiles. The player, or an auto-pick process, uncovers a set number of squares, each holding its own multiplier value, and hidden "keys" among the tiles can unlock an additional, larger prize. A random multiplier is applied to the round's total at the start, before any tiles are revealed. Of the four bonuses, Billy Bones' Map has historically produced the highest maximum win.

It triggers on 2 of 54 segments, 3.70% per spin, averaging one hit every 26.6 rounds in the 90-day sample, with a longest observed gap of 197 rounds.

Across 2,995 hits in 90 days, the settled multiplier had a median of 77x, an average of 170.5x, a 90th percentile of 204x and a maximum of 5,040x, the highest median of any of the four bonuses. Zooming out to the full history, Billy Bones' Map also holds the single biggest result our tracker has ever recorded: 7,028x on 2026-03-21, plus a 5,065x on 2026-04-28 and a 5,050x on 2026-02-05.

How does Ben's Lost Marbles work?

Ben's Lost Marbles plays out as a pinball or pachinko-style drop. A dice roll sets how many marbles are released, and each one lands in a slot carrying its own multiplier; the values from every marble add together into the round's final payout.

It shares Billy Bones' Map's odds: 2 of 54 segments, 3.70% per spin. Our 90-day sample averaged one hit every 26.8 rounds, with a longest gap of 226 rounds.

Ben's Lost Marbles sits in the middle of the pack on payout size. Its 2,978 hits over 90 days produced a median of 20x, an average of 24.7x, a 90th percentile of 42x and a maximum of 830x, well below Billy Bones' Map or Captain Flint's Treasure but noticeably ahead of John Silver's Loot.

How does Captain Flint's Treasure work?

Captain Flint's Treasure is a path game across several levels of barrels. Each barrel a player advances through hides either a multiplier, which is banked onto the running total, or a skull, which ends the round immediately; the first few levels are built skull-free so the round always banks something before risk enters the picture.

It is the rarest segment on the wheel by a wide margin: 1 of 54, 1.85% per spin. Our 90-day sample averaged one hit every 53.5 rounds, with the longest gap running to 341 rounds. Using the segment probability, the chance of going 50 rounds without seeing it is (1 minus 0.0185) raised to the 50th power, about 39%, which lines up with an average gap in the low fifties.

Rarity has not stopped Captain Flint's Treasure from paying well. Over 1,490 hits in 90 days it produced the highest average of the four bonuses at 174.2x, with a median of 129.5x, a 90th percentile of 312x and a maximum of 2,305x. It has not, however, produced the single biggest all-time result: that title belongs to Billy Bones' Map. Captain Flint's Treasure's best all-time hits, 6,535x on 2026-01-14 and 6,222x on 2026-02-10, both sit below Billy Bones' Map's 7,028x. Rarity raises the typical size of a hit; it does not by itself guarantee the largest win on record.

What is the Top Slot and how does it boost a payout?

The Top Slot is a separate reel mounted above the main wheel. Before every spin it draws a bet spot, either one of the four numbers or one of the four bonuses, and a multiplier. If the main wheel then lands on that same spot, the multiplier is applied to whatever that segment would normally pay.

The mechanic works the same way for numbers and bonuses. A wheel result of "1" matched with a Top Slot value of 5x pays 5x instead of the base 1:1. A "2" matched with a 5x Top Slot pays 10x instead of 2:1. The same logic applies inside the four bonus rounds, where a Top Slot match lifts the values feeding into John Silver's Loot, Billy Bones' Map, Ben's Lost Marbles or Captain Flint's Treasure before they settle.

Measuring exactly how often the Top Slot fires is harder than it sounds. The feed flag meant to record a match, is_top_slot_matched, is populated on only a small slice of rows: 295 true against 1,258 false out of roughly 79,700 rounds in the last 90 days, with the rest unlabeled. That makes it a lower bound, not a real match rate. A more reliable signal is how often a number segment actually paid above its plain base value, which captures every boosted hit regardless of whether the flag was set.

Number segment	Share of hits paying above base (90d)
"1"	26.99%
"2"	13.81%
"5"	6.33%
"10"	13.36%

Those shares are well above what a simple one-in-eight guess (one Top Slot bet-spot matching out of eight possible categories) would predict, especially for "1". The exact underlying odds of a Top Slot match are not confirmed in our sources, so treat the table above, not a theoretical match rate, as the working figure.

How are Treasure Island bonus bets settled?

A bonus only pays if a bet was placed on that specific spot before the wheel stopped. A bet on the number 10 does not participate in Ben's Lost Marbles, and a bet on John Silver's Loot does not participate in Billy Bones' Map. If the wheel lands on a bonus nobody bet, the round simply moves on for that player.

The payout is stake multiplied by the bonus's final settled multiplier: a 1-unit bet on Captain Flint's Treasure that resolves at 130x returns 130 units. Bet limits run roughly from $0.10 to $5,000 per spot, though the exact range varies by operator. Betting rounds typically run 30 to 60 seconds when only numbers are in play, and longer once a bonus round is triggered and has to play out on screen.

There is no bonus buy in Treasure Island. It is a live stream with a physical wheel, and the only route into any of the four features is a bet on that spot ahead of the spin. The step-by-step version of placing that bet is covered on the how to play page.

Which Treasure Island bonus pays the most?

The answer changes depending on whether "most" means frequency, a typical hit, or the biggest number the game has produced.

Bonus	Probability	Median (90d)	Average (90d)	90th pct	Max (90d)	All-time record
John Silver's Loot	7.41%	7x	11.9x	21x	1,000x	-
Billy Bones' Map	3.70%	77x	170.5x	204x	5,040x	7,028x (2026-03-21)
Ben's Lost Marbles	3.70%	20x	24.7x	42x	830x	-
Captain Flint's Treasure	1.85%	129.5x	174.2x	312x	2,305x	6,535x (2026-01-14)

John Silver's Loot hits most often and asks the least patience, but its median of 7x is the smallest of the four by a wide margin; it is the bonus you land in regularly without expecting a dramatic swing. Billy Bones' Map has the best median payout on a hit and the highest all-time result our tracker has recorded. Captain Flint's Treasure has the best average of the four, driven by its rarity concentrating large results into a smaller sample, and it also carries the widest gap between a typical and an exceptional hit (median 129.5x against a 90th percentile of 312x). Ben's Lost Marbles sits between the extremes on every measure.

None of the four beats the house edge over time. Treasure Island's published theoretical RTP runs roughly 96.51% to 96.55% depending on the exact bet and version, with our own game configuration listing 96.50% as the headline figure; we do not publish a separate RTP per individual bonus because the sample sizes above are not large enough to reconstruct one reliably. The full RTP breakdown by number bet lives on the RTP page.

What is the biggest Treasure Island win on record?

7,028x, a Billy Bones' Map result recorded on 2026-03-21. It sits ahead of four other results in our tracker's history: a 6,535x Captain Flint's Treasure on 2026-01-14, a 6,222x Captain Flint's Treasure on 2026-02-10, a 5,065x Billy Bones' Map on 2026-04-28, and a 5,050x Billy Bones' Map on 2026-02-05.

The current version of the game carries a design maximum of 20,000x, so even the biggest hit we have tracked has room below the ceiling; an earlier version of Treasure Island topped out lower. Big results are uncommon by design. Over the last 90 days, 1,962 rounds, 2.5% of the total, paid 100x or more, and only 262 rounds, 0.33%, reached 1,000x or higher. Most spins settle far below either threshold, which is exactly what a wheel weighted toward small numbers should produce.

Does a bonus drought mean one is due?

No. The wheel has no memory, and every spin is an independent event where each of the 54 segments carries the same fixed odds it always has, regardless of what has or has not landed recently.

Our 90-day sample recorded a 341-round stretch with no Captain Flint's Treasure at all, well past its average gap of 53.5 rounds. At 1.85% per spin, the chance of a streak that long happening by pure chance is small but real, and it does not change the math on the next spin: the probability stays 1 in 54, exactly what it was before the streak began and exactly what it will be after Captain Flint's Treasure finally lands again.

The same logic runs the other direction for the game's overall bonus rate. Going 20 rounds with no bonus at all has a probability of about 2.6%, using (1 minus 0.1667) raised to the 20th power; a 10-round dry spell has a probability of about 16.2%. Neither figure is evidence of anything except ordinary variance. Chasing a cold bonus by betting on it every round through a long gap has a real cost in stake, separate from whatever the odds are doing, and that bankroll question is covered on the strategy page. Set a budget before playing, treat any live game show as entertainment rather than income, and use tools like those covered on our responsible gambling page if a session stops feeling fun.

How to check today's Treasure Island bonus history

The live tracker pulls from the same feed behind every number in this article, so "today" reflects rounds as they finish. The segment wheel widget shows each result's share against the theoretical odds over a window you choose; the bonus stats panel breaks out hit counts and paid multipliers per bonus; the drought tracker shows how many rounds it has been since each bonus last landed against the longest gap on record; and a probability calculator answers "what are the odds of no Captain Flint's Treasure in the next N rounds" style questions directly.

Use the history to set expectations, not to time a bet. Knowing John Silver's Loot typically pays 7x means a 200x result registers as the outlier it is, and knowing Billy Bones' Map averages one hit every 26.6 rounds means a 100-round wait is unusual but well inside what the same 90-day sample already produced elsewhere on the wheel.

Where these numbers come from

Wheel composition, Top Slot rules and theoretical RTP figures come from Pragmatic Play's published game rules and help screens, alongside our own collector configuration, which matches the observed 90-day segment shares closely. Some bonus-round thresholds and exact mechanics are described only in general terms here because third-party reviews disagree on specifics across the game's earlier and current versions. Observed multipliers, gaps, hit rates and record payouts come from the LiveCasinoData Treasure Island tracker, covering 211,021 rounds logged since the collector started recording this game, with 90-day and 30-day figures as of 2026-08-28. Those figures update as new rounds arrive; the live page always carries the current values.

Frequently asked questions

Which Treasure Island bonus pays the most?

On a typical hit, Billy Bones' Map, with a 90-day median of 77x and average of 170.5x. Captain Flint's Treasure has the highest average of the four (174.2x) because it is rare enough that a few large results pull the mean up, but its median (129.5x) sits behind Billy Bones' Map. Ben's Lost Marbles (median 20x) and John Silver's Loot (median 7x) pay far less on a typical round.

How often does a bonus hit in Treasure Island?

Any of the four bonuses lands on 9 of 54 segments, 16.67% per spin, close to one spin in six. Our last 30 days (37,779 rounds) measured 16.76%. Individually: John Silver's Loot 7.41%, Billy Bones' Map and Ben's Lost Marbles 3.70% each, and Captain Flint's Treasure 1.85%, roughly once every 54 spins on average, though gaps well past 300 spins happen.

What does the Top Slot do in Treasure Island?

Before each spin, a reel above the wheel draws a bet spot and a multiplier. If the main wheel lands on that same spot, the multiplier applies to the payout, whether it is a number or one of the four bonuses. Our data shows number segments paying above their base value on anywhere from 6.33% ("5") to 26.99% ("1") of their hits over 90 days, evidence of how often the Top Slot boosts a result.

What is the biggest win recorded in Treasure Island?

The largest settled multiplier in our tracker is 7,028x on Billy Bones' Map, recorded 2026-03-21, ahead of two Captain Flint's Treasure results at 6,535x and 6,222x. The design cap on the current version of the game is 20,000x, so none of these all-time results has reached the maximum.

Can you buy a bonus round in Treasure Island?

No published bonus buy exists for Treasure Island. It is a live game show with a physical wheel, and the only way into John Silver's Loot, Billy Bones' Map, Ben's Lost Marbles or Captain Flint's Treasure is a bet on that spot before the spin and a wheel that lands there.
