Frequently Asked Questions
Is this slot machine truly random?
Yes. Each reel's symbol is determined independently using Math.random() before the animation starts. The weighted probabilities mean common symbols (Cherry, Lemon) appear more often than rare ones (Diamond, Seven), which is how real slot machines work.
What is the jackpot in this slot machine?
The jackpot is three Lucky Sevens (7 7 7) on the payline. It pays 300× your bet, so a 10-credit bet wins 3,000 credits. The probability of hitting the jackpot is approximately 0.009% per spin — rare but possible!
What does 2-of-a-kind pay?
Two matching symbols on the payline pay a smaller amount, but only for Cherry, Lemon, Orange, Grape, and Star. Bell, Diamond, and Seven require three of a kind to win. Check the Payout Table at the bottom of the page for exact multipliers.
Can I win real money?
No. This is a purely virtual slot machine for entertainment only. Credits have no monetary value. No real gambling is involved at any point.
What happens when I run out of credits?
When your credit balance reaches zero, a "Play Again" button appears that resets your balance to 100 credits so you can continue playing.
