The return is 96.01 % exactly, the same at every bet; the game's rules show it rounded, 96.01 %. 70.86 % of it is paid by the spins and 25.14 % by the Wild Respin.
Paytable
Three of a kind on a line pays; wins on different lines add. The lines are the three rows and the two diagonals. The wild, BOSS, stands in for every symbol, and three wilds on a line pay as the top symbol, Tijori. Prizes are multiples of your total bet.
| Symbol | 3 on a line |
|---|---|
| BOSS (wild) | 40× |
| Tijori | 40× |
| Gold biscuits | 12× |
| The tijori's keys | 8× |
| Aviators | 6.4× |
| Cream sedan | 4.8× |
| Monsoon umbrella | 3.2× |
| Rotary telephone | 1.6× |
Full Reels ×2
When all nine cells show one symbol (the wild standing in), every line's prize is multiplied by 2. About 1 in 1,091.3 (0.09 %) spins show one.
Wild Respin
A winning line with a wild on it starts the Wild Respin: that line stays frozen in place and the other six cells spin again, free. Every line of the new screen pays, the held line included. If the respin shows another winning line with a wild on it, that line is held instead and the reels spin again; otherwise the round ends. When one screen has more than one winning line with a wild, the line that pays most is held (the lower line number on a tie). The spin and its respins are paid as one round.
| Starts | 1 in 30.5 (3.28 %) spins |
| Respins per feature, on average | 1.23 |
| Three respins or more | 1 in 23.9 (4.19 %) features |
| Average feature | 7.66× the bet, after the spin that starts it |
Buy Bonus
For 14.4× the bet, Buy Bonus plays a spin that is certain to start the Wild Respin: its screen is drawn only from the screens that show a winning line with a wild on it, each as likely as in play, and the Wild Respin follows as above. It never pays nothing, because its opening line always wins.
| Price | 14.4× the bet |
| Pays nothing | never (0%) |
| Pays back its price or more | 1 in 3.1 (31.81 %) |
| Pays twice its price or more | 1 in 11.6 (8.59 %) |
| Average return | 13.85× the bet (96.19 %) |
Maximum win
A round pays at most 500× the bet, the spin and all its respins together; the screen that reaches it pays exactly up to it, and the round ends there. One screen pays at most 400× the bet, so only a long Wild Respin reaches the maximum: about 1 in 3,123,931,975.1 (0.00 %) spins, or 1 in 102,520,286.7 (0.00 %) purchases.
How often a round pays
The chance that a round — a spin at the bet, or a purchase at 14.4 times it — pays at least a given multiple of the bet.
| At least | Spin | Buy Bonus |
|---|---|---|
| 1× the bet | 1 in 7.6 (13.21 %) | always |
| 2× the bet | 1 in 9.4 (10.59 %) | always |
| 5× the bet | 1 in 19.9 (5.03 %) | 1 in 1.4 (72.28 %) |
| 10× the bet | 1 in 44.9 (2.23 %) | 1 in 2.4 (41.93 %) |
| 20× the bet | 1 in 129.8 (0.77 %) | 1 in 5.8 (17.27 %) |
| 50× the bet | 1 in 824.7 (0.12 %) | 1 in 28.9 (3.46 %) |
| 100× the bet | 1 in 7,731.9 (0.01 %) | 1 in 274.5 (0.36 %) |
| 200× the bet | 1 in 699,745.4 (0.00 %) | 1 in 23,181.1 (0.00 %) |
| 500× the bet | 1 in 3,123,931,975.1 (0.00 %) | 1 in 102,520,286.7 (0.00 %) |
Certificate
This game's maths is certified in-house by Wynbook, the game's studio; no outside laboratory is involved. The figures above come from independent computations that must agree:
| Exact return (Go solver) | 96.005987% |
| Exact return (independent Python) | the same figures, to 1e-9 |
| Exact round distribution (this page's tables) | 96.005987% before the maximum win, 96.005986% with it |
| Simulation | 200,000,000 spins: 95.9626% (99% interval 95.8824% – 96.0429%) |

The simulation played the game's own reels, weights and paytable through the engine that settles real rounds.
