How slot wins are calculated


Understanding the mechanics of calculating winnings helps the player assess risk, choose suitable bets and predict the potential result. Despite the external simplicity, the slots are based on clear mathematical algorithms and predetermined payout coefficients.

1. Basic formula for calculating winnings

The basic calculation for most classic and video slots looks like this:
  • Line Bet × Symbol Factor = Line Win

Ubi:
  • Bet per line - the amount bet per payline.
  • Symbol Factor-The multiplier specified in the paytable for a particular combination.

Example: bet per line - 0.50 AUD, a combination of five identical characters with a multiplier × 100. Win = 0.50 × 100 = 50 AUD.

2. Payline Number Role

If all lines are bet, the total gain is calculated by summing the results for each line. With incomplete activation of lines, the potential gain decreases, but the size of the bet also decreases.

3. Scatter symbols and their features

Scatter are paid regardless of the lines and often multiply the total rate per spin rather than the rate per line. For example, dropping three Scatters with a multiplier of × 5 at a total bet of 2 AUD will give 10 AUD.

4. Multipliers and bonus features

Wild with a multiplier doubles or triples the win along the line on which he participates.
Free Spins can have additional multipliers, such as × 2 or × 3 for all wins in a round.
Bonus games use separate mechanics: selection of items, wheels of fortune, progressive multipliers.

5. Progressive and fixed jackpots

In the case of a jackpot, the winnings are calculated at a predetermined amount (fixed) or at the current accumulated bank (progressive). Progressive amounts are displayed in real time and paid in full, regardless of the rate, if the conditions for hitting are met.

6. Return to Player (RTP) and variance

Although RTP is not involved in the direct calculation of winnings for a specific spin, it determines the mathematical return at a distance. Dispersion affects the frequency and magnitude of winnings: highly dispersed slots give large, but rare payments, low-dispersed slots give smaller, but more often.

Conclusion:
  • Each win in the slot is the result of applying fixed odds to the bet, taking into account paylines, Scatter, multipliers and bonus functions. Having studied the paytable and the mechanics of the selected game, you can understand in advance the range of possible payments and more consciously approach the choice of bets.
