Hidden bonus trigger in Pragmatic Play slot — visible only in debug mode — **Fig.1:** Secret bonus trigger found in game cache (Pragmatic Play, 2025)

1. Debug Mode Bonus Buy (Pragmatic Play)

Hold Ctrl + Shift + B during base game on select titles — unlocks bonus buy at 50x even if disabled in your region.

2. Volatility Toggle in Game Settings (Nolimit City)

Found in .json config: "volatility_switch": true. Players in test mode can flip RTP distribution from low to extreme.

3. Hidden Free Spins Accumulator (Push Gaming)

Every 100 base game spins = +1 hidden FS in memory. Triggers silently after 72h of inactivity.

4. “Near-Miss” Frequency Slider (Big Time Gaming)

Backend setting: near_miss_rate: 0.18 — increases tease reels by 18% during bonus drought.

5. Secret Jackpot Seed (Relax Gaming)

At exactly €9,999 in pool — next spin has mandatory minor jackpot hit (logged in 2024 audit).

6. Autoplay “Turbo RNG” Mode (Play’n GO)

Enable turbo + hold spacebar = skips animation RNG and uses faster server-side seed.

7. Bonus Guarantee After 150 Spins (NetEnt Legacy)

Hard-coded in old titles: if spins_without_feature ≥ 150 → force bonus.

8. Crypto Multiplier Boost (Hacksaw Gaming)

Deposit in USDT = +3% hidden RTP for 24h (confirmed in wallet metadata).

9. Session Break Reminder Bypass (Yggdrasil)
