About David
David runs SpinVerdict's slot-review desk and has reviewed more than 600 slots in nine years. His specialism is slot mathematics, extracting published RTP, modelling realistic session variance, decomposing bonus-round economics, and flagging multi-RTP variants that operators load at the lower configuration. He writes the SpinVerdict slot-volatility methodology and is the first port of call inside the editorial team when a new game from Pragmatic Play, Hacksaw Gaming or Big Time Gaming launches. David takes the published RTP of every slot he reviews and tests it against several thousand simulated spins to confirm hit-frequency claims; where his test results contradict the published RTP, he says so. He is quietly suspicious of bonus-buy mechanics, has a soft spot for low-volatility classics, and writes with technical precision and a dry sense of humour about the more outlandish max-win caps.
