What Is The Slot Calculator?

Our online slot calculator lets you calculate the real value of free spin offers that the casino provides and how to make the most of them to maximise your chances of beating the online casinos.

  • Qualifying Deposit
    The is the amount of your initial deposit without any bonus funds.
  • Free Spin Value
    The is the amount that each spin costs. If you receive 10 spins on Book Of Dead slot at 0.10 each then the total value of all of your spins is 1.00. You should write in the value that each individual spin costs.
  • Number Of Free Spins
    This is the total amount of free spins given.
  • Deposit / Bonus RTP
    Wagering requirements are also sometimes referred to as the "playthrough amount". This is the multiplier amount that your free spin winnings amount needs to be wagered before being released as cash that can be withdrawn. Wagered means the amount bet regardless of how much is won or lost.
  • Slot RTP
    This is the RTP (Return To Player) amount that the slot you have free spins on gives.
  • Additional Tips:
    The amount a game can contribute towards your wagering requirements can vary from 100% contribution all the way down to 0%. Generally slots games will contribute 100% with classic table games contributing less. Always make sure you check out the full terms and conditions attached to each casino bonus offer so you can be sure which games contribute the best percentages for maximum chances of reaching the best estimated value.
