Personal testers opinion

It is not bad for playing at the small and medium stakes. At the expense of wild symbols on all reels during the free spins feature can give big winning. A probability to hit any winning next spin is 36.22%. The frequency of triggering the free spins feature is 0.81% (every 123rd spin, statistically). The prize fund is distributed as follows: 65% goes to the payment in the usual spins, and 35% of the pool for bonus features. The wagering rating is 5.4 with 10 max. My maximum winning during the tests was 362x.

Review and recommendations from the testing team

Thunderfist is a quite exciting slot by Netent although it is less popular

  • Despite the pretty weak graphics, the slot has a big potential for big and mega big winning, which is achieved through 243 lines and the possibility of getting one or several wild symbols that wholly or partially (when expanded) cover the reel and a multiplayer up to x4 on free spins feature.
  • When it comes to the main game, the slot is quite bad at keeping the balance. Free spins are triggered in series, either with small intervals or with a long betting period.
  • The slots winning potential for free spins feature is huge. During testing in a game with real money, it was possible to get a combination of 3 full wild symbols with one part (not extended) and the other a top symbol and all with x4 multiplayer.
  • With the multiplayer, the slot is not cheating, i.e. the slot gives out x4 not only for small wins but also for big ones.
  • During one free spins bonus feature, it is possible to get several big wins.
  • The recommended reserve of bet balance is a minimum of 200 bets. Keep an eye on the free spins triggering, and if there is no feature for 100 bets, then it is quite risky to continue the game session.

Netent declares the following probabilities

  • The total percentage of the return (RTP) in the slot is 96.7%. The slot machine pays 64.3% in the main game and reserves 32.4% for the bonus free spins feature.
  • The probability of getting any winning (hit) in the usual spins - 64.3%. During the free spins feature - 41,8%.
  • The probability of triggering the free spins feature is 0,9%.
  • Maximum winning per single spin is 1 121 500 coins.
