Marcus Feld

Bonus analyst at cryptocodes.ai

Marcus writes every bonus page on cryptocodes.ai and builds the calculators behind them. He has spent six years working on casino bonus terms, and his rule for this site is simple: a figure the operator does not publish is not printed as if it did.

How Marcus works

Every bonus page starts the same way: Marcus registers with the code, deposits, and records what actually credits — then reads the operator's help centre, terms and VIP pages line by line and writes down where each figure came from. Where an operator publishes nothing, the page says so rather than borrowing an estimate from another affiliate site.

He also built the calculators and simulators on this site. They exist because a rakeback percentage or a wagering multiplier means little until you price it against the house edge of the games you play, and most bonus pages never do that arithmetic.

Before cryptocodes.ai he worked on bonus terms and player-value modelling for casino affiliates, which is where the habit of asking "a percentage of what?" comes from.
