Online slot games that feature ways to win don't require symbols to line up in order to get a payout. Instead, winning combinations can be made with matching symbols landing across the reels in any direction. Ways to win on the Reel Rush slot basically means that there are 3,125 possible combinations on the reel's 5x5 setup (5x5x5x5x5 = 3,125) and the mechanic is in fact only available on 5-reel slot games. The full 3,125 ways to win in Reel Rush is activated during the Free Spins round.
