How to Calculate Slot Machine Odds


Probability of winning

Probability is an important concept for calculating the odds of slot machine games. While slot machine odds used to be relatively simple to calculate when there were three reels and ten symbols per reel, they have become much more complicated as video slots and electromechanical slot machines became more popular. Probability is the branch of mathematics that calculates likelihoods. You should know at least a little bit of mathematics to be able to calculate slot machine odds.

Scatter symbols

Scatter symbols in slot machines are the symbols that appear on the reels without a payline. These symbols can be the most valuable in a slot game, so finding them is the key to winning. However, you must check the paytable of each game before you start playing. This way, you will know which symbols to look for.

Scatter symbols may have different functions in different slot games. In some games, landing three or more of these symbols will trigger a bonus round. In other games, you will receive a certain number of free spins. In any case, the payout will be much higher than in a normal game. In addition, scatter symbols are often represented by graphics that relate to the overall theme of the game. For example, the Dragon’s Return game by Konami has scatter symbols that trigger free spins. And in the Buffalo line of games by Aristocrat, landing three or more coins will trigger a scatter bonus feature.

Scatter symbols can also be used to win extra spins. Moreover, they are usually the highest paying symbols, meaning that players will earn more money when they land scatter symbols. Since the payout is based on the number of symbols and not the number of paylines bet, scatter symbols can help players win huge payouts. However, they also have a downside – they can lead to more false wins and decrease the frequency of payouts.

Return to player

A Return to Player slot is a casino game that has a high return to player percentage. The RTP percentage is an indicator of how much a player will lose in a game over a long period of time. Knowing this percentage allows players to better plan their bankroll and betting strategies. It is also a mathematical advantage for online casinos.

A Return to Player slot pays out a higher percentage of winnings than the average slot game. This is a benefit for players as it reduces the House Edge, the mathematical advantage the casino holds over the player. This percentage is usually ninety-four percent or higher. If you are planning to play at an online casino, it is best to look for Return to Player slots that are above ninety percent.
