Review and recommendations by the testing team

WinningThis slot has a nice design; the sound is also quite comfortable and does not cause irritation.

  • On this slot, there are no bonus games or free spins, so in the usual spins, the slot does not let the balance to sink much like in other games, where it then compensates in the bonus game, but it will not multiply the balance either.
  • There is no potential for a really big win on this slot and you should not expect a combination with a win above x250. The average value of the win with two wild symbols ranges from 20 to 80 bets, but the frequency of their issuance may please.
  • This slot is quite suitable for games with bonus funds but for fairly short distances, also when playing for real money, we would recommend playing at fairly short distances in order to get 2-3 wins in average values and then leave the slot. After that, it begins to withdraw, until the balance is reset. This slot is created more for entertainment at low rates, than for the win issuance potential.
