Game Mechanic

1. Player places a bet
2. Server generates a secret 12-character key (A–Z, 0–9 = 36 possible characters)
3. Player guesses one character position at a time
4. Correct guess: positive multiplier added + character revealed
5. Wrong guess: penalty applied + FBI trace percentage increases
6. Game ends when FBI trace reaches ≥ 100% (busted) or all 12 characters are guessed (50× jackpot!)
7. 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)

When a player guesses correctly, the multiplier is drawn from this pool:

Multiplier	Weight	Probability
0.5×	100	10.0%
1.0×	250	25.0%
1.5×	200	20.0%
2.0×	150	15.0%
3.0×	100	10.0%
4.0×	80	8.0%
5.0×	60	6.0%
7.5×	40	4.0%
10.0×	20	2.0%

FBI Trace Mechanic

• Each guess (correct or wrong) increases the FBI trace percentage
• Wrong guesses increase the trace more than correct guesses
• Trace increase per guess is determined by the provably fair RNG
• When trace reaches ≥ 100%, the game is over (busted)

RTP Variant Differences

Setting	RTP_92	RTP_94	RTP_96	RTP_97
Base trace per correct guess	8–12%	6–10%	5–8%	4–7%
Base trace per wrong guess	15–25%	12–20%	10–18%	8–15%
Wrong guess penalty multiplier	0.3×	0.25×	0.2×	0.15×
Avg rounds before bust	~5	~6	~7	~8

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× bet

TIP

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.
