Slot Summary

Matching three, four, or five symbols gives Scratch King the logic of a slot while preserving the quick reveal-and-resolve character of a digital scratch card. Spinoro released it in 2021 as a medium/high-volatility instant game, with a wild helping complete matches and three bonus keys opening a separate chest prize. Its identity comes from that hybrid rather than a conventional spinning-reel loop.

How It Plays

Each round checks matching symbols from left to right, with wins formed by three, four, or five matching positions. Pattern completion, rather than payline selection, sets the base rhythm.

The wild acts as a substitute that can complete a valid match. Four matching symbols raise the potential return, while five matching symbols apply the larger stated multiplier.

Features & Win Potential

Wild substitution concentrates the main feature value inside ordinary symbol matching. It matters when a sequence falls short of the three, four, or five symbols required for a win.

Bonus symbols create a second objective outside normal matches. Gathering the required keys moves the round into the Bonus Game instead of merely increasing the current symbol payout.

Wild Symbol Medium/High 5 Reels Bonus Game Bonus symbols

Bonus & Free Spins

Landing three bonus keys unlocks the treasure chests and produces another cash prize. The bonus therefore depends on collecting its trigger symbols within one round.

How this works

Each simulated spin either misses or returns a win drawn from a log-normal distribution, with the hit rate and spread set by the slot's volatility tier (Medium-High). The model is calibrated so the average return equals this slot's published RTP (93.04%), with wins capped at its top multiplier (10,000×).

This is a simplified, parametric model of the game's math — not its real paytable. It exists to make the house edge visible over many sessions, so the numbers above are averages across thousands of runs, never a forecast of one.

This is math, not a prediction. Real sessions vary wildly, and no strategy changes a game's built-in house edge. Play for fun, set limits, and never bet more than you can afford to lose.
