Beanfall

Place your chips, pull the lever, and watch hundreds of beans cascade through the pegs of a bean-machine — building a bell curve before your eyes.

How to play

Before each wave you stake chips on the outcome bins of a Galton board (a peg field where beans bounce left or right). Drop the wave and the beans pile up into a histogram that approximates a bell curve. A bet wins if its bin is among the three fullest of the wave. Center bins pay small but often; tail bins pay big but rarely. Survive the waves with chips in the bank.

• Each wave gives you a fixed pool of chips to place.
• Payout multipliers are shown on each bin — tails pay the most.
• Run your bank to zero and you bust out.

Controls

• Desktop: left-click a bin to add a chip, right-click to remove one, then click Drop.
• Phone & tablet: tap a bin to add chips and use Clear bets to reset, then tap Drop.

Game modes

• Board sizes of 8, 12 or 16 rows, each in Daily (shared) or Practice (random).

Tips & strategy

• The center bins fill most often, so spread the bulk of chips near the middle.
• Sprinkle a few chips on a tail bin for an occasional high-multiplier payday.
