10stake
Choose a stake to begin.
Three reels, five lines and the old symbols polished up: sevens, ship's bells, bars, moons and meteors. The lens is wild, and any line that uses a lens pays double.
The quickest instrument in the hall: one press, one answer. It suits a few rounds while the kettle boils.
Nothing is hidden. What you see on the three reels is the whole round.
Long-run return is what the game gives back on average over millions of rounds, checked by simulation. Any single evening can land far above or below it.
These are the exact numbers the game uses. Every round is drawn fresh by your browser's secure random number generator, and nothing that happened before changes what happens next.
Returns are shown as multiples of your total stake. A line that uses a lens pays double.
