The simulator offers games on the lower reels( bet 4 kc) that can block and thus increase the chance of winning. Wins are stored in MultiWin, which allows the game on the upper reels( bet 4+8 or 4+16 with jockers support), which achieves a higher percentage. The prize can be multiplied by a risk-taking or lose it the same way. You have got a wallet with an initial investment of 500kc a daily bonus credit to 500kc.
It is just game without hazard of losing your money :-)
