Breaching the mainframe…
Wins pay when a symbol appears anywhere among a payline's 5 sampled positions — matches don't need to be left-to-right. Every selected line is evaluated on every spin and all line wins are added together. Multipliers below apply to your bet per line.
3, 4 or 5 alarms anywhere on the grid award 1, 5, or 15 free spins. Free spins play at the bet that triggered them and never cost anything from your balance.
Access Granted substitutes for every symbol except the Silent Alarm. Land it 2–4 times on a line for its own payout. Land 3 or 4 on a single line to earn Vault Cracking bonus picks (1 pick for 3, 5 picks for 4). Land all 5 on one line to trigger MAINFRAME BREACH — the full local jackpot meter, paid instantly.
Crack your earned vaults one at a time. Every vault is a guaranteed win worth roughly 2×–20× your triggering bet — there is no losing pick.
