Review and recommendations from the testing team

  • King Colossus slot has a very good potential of giving out winnings of 100x-150x bets (from one bonus feature). The slot is not able to trigger the biggest prizes (only while giving a series of bonus features).
  • In the usual spins, King Colossus gives out only small wins in the range of the normal bet size to just a few bets, and less often - wins can reach 10x bets, maximum payout received in those spins was 27x total bets.
  • When bonus feature (free spins) is triggered, 5 spins are given (there is no re-trigger feature, but you can catch the symbol that is adding one spin). During the free spin the slot gives out 2 guaranteed bonus wild symbols (only in the first and fifth reels), you can also get massive king symbol (3 * 3 size), which can take its position on 2,3 and 4 reels. The maximum possible payout during free spins is 100x bets per spin. The average total winnings during testing were 20x-60x and less often managed to get wins of the 90x-120x total bet, and the maximum - more than 140x bets.

King Colossus can easily be recommended playing with bonus money. While playing for real money, not only for the great potential for giving out winnings within 100x bets, also how often those winnings are given, as well as the frequency of bonus features triggering, I would recommend short gaming sessions using progressive betting strategies. Long game sessions are possible trying to get the maximum from King Colossus, but you need to keep your balance in the usual spins while waiting for the top combination in free spins.
