AI-Powered Casino Bonus Analyzer (2026)

Step 1: Paste or enter bonus terms

Copy any casino welcome bonus T&C: the full block including wagering requirement, max bet, game contribution table, expiry, and win cap. Paste it into the text tab. You need at least 50 characters; the full T&C paragraph gives the best accuracy.

Step 2: AI extracts 8 structured fields

The Claude API reads your text and pulls out: wagering multiplier (e.g. 35x), wagering base (bonus only vs bonus + deposit), max bet per spin, slots contribution %, expiry days, max cashout cap, min deposit, and excluded payment methods. Each field is flagged as AI-extracted until you verify it.

Step 3: EV formula runs, grade assigned

The analyzer runs: EV = Bonus Amount minus (Wagering Base times Multiplier divided by Contribution times House Edge) minus Max Bet Drag minus Win Cap Discount. The result is compared against grade thresholds: Grade A is above +20% EV, Grade F is below minus 20% or any critical flag. You get a single letter and a plain-language verdict.

The EV formula, step by step

Expected value is the average amount you end up with after completing all wagering. A 100 dollar bonus with 35x wagering on 96% RTP slots requires 3,500 dollars of turnover. At 4% house edge, the expected loss is 140 dollars. Subtract from the 100 dollar bonus: EV is minus 40 dollars. Most welcome bonuses have negative EV. The question is how negative, and whether other red flags make it worse.

When bonuses have positive EV

Positive EV bonuses exist: low wagering (under 20x), applied only to the bonus amount, with high slots contribution and no win cap. Example: a 50 dollar bonus at 15x wagering on slots only: turnover 750 dollars, expected loss 30 dollars, EV plus 20 dollars. Grade A. These are rare and casinos change terms quickly. The analyzer catches them automatically.

Bonus-only vs bonus + deposit wagering base

The wagering base is the multiplier applied against. A 100 dollar bonus at 35x on bonus-only means 3,500 dollars turnover. The same 35x on bonus + deposit (200 dollars total) means 7,000 dollars. The second costs twice as much in expected losses. Always check which base applies: it is buried in the T&C and casinos phrase it ambiguously.

Max bet rule: the hidden grind tax

Most casinos cap bets at 3 to 5 dollars per spin during wagering. On a 2 dollar average-stake slot, a 5 dollar cap barely restricts you. But on high-volatility slots where optimal play is 10 to 20 dollars per spin, the cap forces slow grinding at low stakes, killing variance-based strategies. The analyzer flags max bets below 3 dollars as major and below 2 dollars as critical.

⚠Sticky bonus: the most dangerous flag

A sticky bonus (non-cashable) never converts to real money. You wager with it, but only profits can be withdrawn. Effectively you are grinding through wagering requirements using only your deposit, with the bonus acting as a wagering buffer that disappears at cashout. Our analyzer marks sticky bonuses as Grade F regardless of EV, because the bonus value is zero in practice.

⚠Win caps: when a big win gets cut off

A win cap (max cashout) limits bonus winnings. A 500 dollar cap on a 200 dollar bonus means even a 2,000 dollar lucky run only pays 500 dollars. On high-volatility slots where a rare big win is the only realistic path to positive EV, a cap below 3x the bonus amount is a major red flag. The analyzer flags caps below 3x as major and caps below 1.5x as critical.

⚠Game restrictions and contribution traps

Table games at 5 to 10% contribution effectively multiply the wagering requirement 10 to 20 times. A stated 35x requirement becomes 350x to 700x in real table game play. Live casino at 0% means those bets count nothing. The analyzer shows your effective contribution factor in the EV breakdown and adjusts the house edge calculation accordingly.
