Point stealing is the most common form of fish game cheating that operators overlook. Unlike signal injection or trojan code attacks that target the machine’s payout logic, point stealing targets the player’s credit balance. The cheater adds credits to their own account without paying, or transfers credits from the machine’s reserve account to their player account. Because the point theft happens within the machine’s normal transaction flow, the logs show standard activity. The only signal that something is wrong is a mismatch between the credit intake and the payout output.
In my experience across 50+ venues, point stealing accounts for roughly 35% of all fish game cheating incidents. It is less dramatic than a jackpot trigger — no flashing lights, no alarms — but it is more persistent and harder to trace. A cheater who steals 50 points per session over 20 sessions has stolen 1,000 points worth of play time, and the operator sees only a gradual decline in the machine’s net revenue.
The Three Most Common Point-Stealing Methods
Method one is the fake coin signal. The cheater uses a small device that emits the same electrical pulse the coin acceptor sends when it registers a coin. The machine credits the player’s account as if a coin was inserted. This device can be as simple as a modified TV remote or a purpose-built pulser that attaches to the coin mech wiring. Method two is the wire tap. The cheater connects a device to the communication line between the coin mech and the main board, intercepting the credit signal and replaying it to generate multiple credits from a single coin insertion. Method three is the software glitch exploit, where the cheater triggers a known bug in the game software that causes the credit counter to double or multiply during specific game events.
Each method leaves a different footprint. The fake coin signal shows up as a sudden increase in session length without matching cash intake. The wire tap shows as a mismatch between the coin mechanism count and the board’s credit register. The software exploit shows as an unusually high number of “bonus credit” events in the machine log.
Why Standard Audit Procedures Miss Point Stealing
Most operators audit fish tables by comparing daily cash intake against machine-reported revenue. This detects large-scale theft — missing cash boxes, manipulated meter readings. It does not detect point stealing because the machine registers the credits as legitimate. The machine believes it received a coin pulse, so it records revenue. The cheater did not actually insert a coin, but the machine’s log shows a coin event. The cash count at the end of the day matches the coin acceptance count. The only discrepancy is between the coin acceptance count and the actual coins in the cash box — and that discrepancy is usually attributed to counting errors.
How the Anti-Cheat Device Detects and Blocks Point Stealing
The Gen2 device monitors three specific signals: the coin mech pulse line, the communication bus between the mech and the board, and the credit register update commands. When it detects a coin pulse that does not match the expected electrical signature of a genuine coin insertion — wrong voltage, wrong duration, wrong timing relative to the previous insertion — it blocks the pulse from reaching the board. When it detects a replay attack on the communication bus — identical credit commands repeated at unnatural intervals — it blocks the replayed commands. When it detects an unexpected credit register modification that does not match the coin mech input rate, it flags and blocks the modification.
In a venue in Lima, Peru, the operator had been losing an average of $2,800 per month across four fish tables. After installing Gen2 devices, the monthly loss dropped to $340. The operator later found that one of his own staff members had been using a coin pulse device to generate free credits for his friends. The anti-cheat blocked the pulses, and the staff member stopped — not because he was caught, but because his device no longer worked.

Frequently Asked Questions
Q: Can point stealing happen on fish tables that use a card-based credit system?
A: Yes. Card systems have their own vulnerabilities — card cloning, balance manipulation through the card reader’s communication line. The Gen2 device monitors those lines as well.
Q: How can I detect point stealing without installing hardware?
A: Compare the coin mech pulse count against the actual coin box contents daily. A consistent discrepancy of 2% or more over a week is strong evidence of point stealing.
Q: Is point stealing done only by external cheaters, or can staff be involved?
A: Both. I have seen cases where staff members use pulse devices to give free credits to friends during their shifts. The Gen2 device blocks these pulses regardless of who initiates them.
Q: Does the device prevent legitimate coin acceptances from being registered?
A: No. The device only blocks pulses that do not match the genuine coin electrical signature. Real coins produce a consistent, predictable pulse. Fake pulses have measurable differences.
