Lotto Madness has 20 paylines, but you don't have to push all 20 at once. You can play as many lines as you want, and the level of participation is limited to the player. The value of the coin you bet is between $0.01 and $10.00, and you can even bet multiple coins on one line if you really want to raise the bet. So the biggest single bet you can make is $100 per line, which means Lotto Madness is a great game for high-volume players.
The bonus symbol in this game is purely used to trigger a bonus round. There are no bonuses for the “just getting” bonus symbol. You either get a bonus game or you can't get anything. Although it is still possible to trigger a bonus game during a free spin, you cannot play the game again. Instead, what happens is that you add a random number of free spins above the current total.
