Increase your wager\n\n Most slot machines will not give out bonuses or progressive jackpots unless you place the highest bet. Since the goal is to beat the house, risk wagering the maximum credit. Although winning a progressive jackpot is not guaranteed, you can increase your chances by betting the maximum credit.

Play Max Lines/Coins: If you're playing a slot with paylines, each one can win independently. That means the more lines you play, the more chances you have of winning. So you're better off playing 20 lines at $0.05 each than one line at $1.00. If you're playing with coins, more coins usually unlock the biggest payouts.
