In slot machines, symbols line up on one or more reels to win credits based on the pay table. The odds of winning are determined by the number and type of symbols on each reel and the size of the bet. In computerized slot machines, a player may bet on multiple lines that run up, down, sideways, or diagonally. When the symbols match on a winning line, the player receives a payout proportional to the amount wagered.

The success of a slot game depends on its ability to attract and keep players. To create a successful game, developers use math and random number generators to produce a series of numbers and then calculate the odds and payout amounts for symbols on the reels. They may also test the game with potential customers to see how they react.
