Two-tier coin pusher machines — where the player plays on a lower deck of coins to trigger drops from a higher-value prize deck — present a unique security challenge. The prize deck is where the real value sits. Players are not just trying to push coins off the edge; they are trying to trigger the mechanism that releases prizes from the upper tier. This two-layer payout structure creates additional attack surfaces that single-deck machines do not have.
I have worked with 12 venues operating two-tier coin pusher machines. The cheating methods used against these machines specifically target the prize deck release mechanism, and standard anti-cheat setups that protect the coin deck often miss the prize deck entirely.
How Cheaters Target the Prize Deck Release
The prize deck on a two-tier machine is typically held in place by a latch or solenoid that releases when a specific condition is met — a coin reaches a sensor, a timer expires, or a token stack reaches a certain height. Cheaters exploit this mechanism in several ways. The most common is the solenoid trigger: a cheater uses a small electromagnetic device placed near the prize deck latch to trigger the solenoid remotely. The latch releases, the prize deck drops, and the cheater collects the high-value prize without having met the game conditions.
A second method is the sensor spoof: the cheater places a reflective or magnetic tag near the prize deck sensor, causing the machine to believe that a coin or token has reached the required position. The machine releases the prize deck prematurely. This method is particularly effective on machines that use optical or magnetic proximity sensors for the prize deck trigger.
Why Standard Anti-Cheat Does Not Protect the Prize Deck
Most anti-cheat systems focus on the coin mech, the communication bus, and the payout controller. These protect the lower deck where coins are played and won. The prize deck release mechanism — the solenoid latch and its sensor — is often outside the protection coverage because it operates on a separate circuit or is controlled by a different board. A cheater who targets the prize deck can bypass the entire coin-level anti-cheat system.
Two-Tier Protection Strategy
The Gen2 system for two-tier coin pushers adds prize deck monitoring to the standard coin-level protection. A secondary sensor module monitors the prize deck latch circuit. When the latch is triggered, the module verifies that the trigger came from the machine’s normal game logic, not from an external signal or sensor spoof. If the trigger is anomalous, the module blocks the latch release and alerts the operator.
In a UK amusement park running 6 two-tier coin pushers, the operator installed the Gen2 system with prize deck monitoring. In the first month, the system blocked 18 attempted prize deck releases that did not match the normal game cycle. The operator estimated that each blocked release saved an average of $40 in prize value. The system paid for itself in under three weeks.

Frequently Asked Questions
Q: How do I know if my prize deck is being cheated?
A: If you find that the prize deck releases more frequently than the machine’s programmed rate — or if prizes are missing from the deck without any corresponding coin activity — the prize deck is being targeted.
Q: Can the prize deck monitoring be added to existing machines?
A: Yes. The Gen2 prize deck module connects to the latch circuit and sensor. No machine modification required.
Q: Do I need one prize deck module per tier or one per machine?
A: One module per machine covers both tiers. The module monitors the single prize deck latch circuit that controls the upper tier.
Q: Will the prize deck monitoring prevent legitimate prize releases?
A: No. The module only blocks releases that do not match the normal game logic pattern. Legitimate releases triggered by coins reaching the sensor or normal timing cycles are unaffected.
