Free Slot and Casino Calculators
Free calculators that show the maths behind casino bonuses and slots, so you know what an offer really costs before you play.
Wagering requirement calculator
Works out how much you must bet to clear a casino bonus, how many spins and hours that takes, and what it costs on average at the game's RTP.
RTP cost calculator
Shows what a slot session costs on average from your bet, spin speed and the game's RTP, and how much more a lower-RTP version of the same slot costs.
How rare is my slot win?
Enter a bonus win and bet to see what share of our recorded slot bonuses it beats, and roughly one bonus in how many pays that much.
