Game Mechanic
- Player places a bet
- Server generates a secret 12-character key (A–Z, 0–9 = 36 possible characters)
- Player guesses one character position at a time
- Correct guess: positive multiplier added + character revealed
- Wrong guess: penalty applied + FBI trace percentage increases
- Game ends when FBI trace reaches ≥ 100% (busted) or all 12 characters are guessed (50× the per-guess stake)
- Player can cash out at any time between guesses
Key Format
- Length: 12 characters
- Character set: A–Z, 0–9 (36 possible characters per position)
- Probability of correct guess: ~2.78% per character (1/36)
Correct Guess Multiplier Pool (RTP_96)
A correct guess pays a multiple of the per-guess stake, not of the whole bet. The values are large because a correct guess is rare — 1 in 36 on the first attempt at a position:
| Multiplier | Weight | Probability |
|---|---|---|
| 7× | 2 | 2.0% |
| 12× | 1 | 1.0% |
| 20× | 30 | 30.0% |
| 30× | 26 | 26.0% |
| 44× | 24 | 24.0% |
| 61× | 17 | 17.0% |
Weights total 100, so weight and probability are the same number.
FBI Trace Mechanic
- A wrong guess raises the trace by an RNG-drawn amount inside the variant's band
- A correct guess halves the trace — it does not raise it
- When trace reaches ≥ 100%, the game is over (busted)
RTP Variant Differences
| Setting | RTP_92 | RTP_94 | RTP_96 | RTP_97 |
|---|---|---|---|---|
| Trace added per wrong guess | 3.05–5.05 pts | 2.75–4.75 pts | 2.20–4.20 pts | 2.50–4.20 pts |
| Trace after a correct guess | ×0.50 | ×0.50 | ×0.50 | ×0.50 |
| Wrong guess penalty | 0.54× stake | 0.50× stake | 0.61× stake | 0.47× stake |
| Correct-guess multipliers | 6–54× | 6–54× | 7–61× | 8–74× |
| Exact RTP | 91.64% | 93.46% | 95.70% | 96.62% |
The penalty column is not monotonic across variants, and is not meant to be: the solver tunes the multiplier pool and the trace band together, and settles wherever the pair lands at target. Only the resulting RTP is a designed value.
Cash Out
- Available after the first guess (correct or wrong)
- Cashes out the current accumulated multiplier × bet amount
- If accumulated multiplier is negative (from penalties), minimum cash out is 0
- Not available if trace is already ≥ 100%
End Conditions
| Condition | Result |
|---|---|
| FBI trace ≥ 100% | Busted — player loses remaining bet |
| All 12 characters guessed | Jackpot — 50× bet awarded |
| Player cashes out | Cash out — accumulated multiplier × bet |
Example Round
Guess 1: Position 3 → 'K' (correct!) → +2.0× → Trace: 6%
Guess 2: Position 7 → 'X' (wrong!) → -0.2× → Trace: 22%
Guess 3: Position 1 → 'A' (correct!) → +1.5× → Trace: 28%
Guess 4: Position 5 → '9' (wrong!) → -0.2× → Trace: 46%
→ Cash out at 3.1× (2.0 + 1.5 - 0.2 - 0.2)
→ Payout: 3.1× betTIP
The optimal strategy balances risk (FBI trace accumulation) against reward (multiplier accumulation). Cashing out early is safer but limits upside. Going for all 12 characters is extremely unlikely but awards the 50× jackpot.
