How Many Marbles?

How many marbles will it take to fill the jar? Make your guess, then watch it pour.

Each round sets a glass vessel on the table. It might be a bathtub, a windmill, a turtle, a rocket, a letter of the alphabet or a maze. Spin it around, size it up against the single marble on the table, and lock in your number. Then the marbles pour in one by one, the count climbs and every guess it passes gets a burst of confetti. The closest guess wins the round.

Play with up to 8 players on one screen, with every guess kept hidden until the pour, or go online: open a lobby, share the room code and everyone guesses from their own screen. Quick Join drops you straight into a public game.

Three ways to play. Classic awards points for the closest guess, with bonuses for landing within 10% or hitting it exactly. In Lives, the furthest guess each round loses a life. In Colours, the jar fills behind a curtain and a wheel picks a colour: how many of that colour are in there?

Over 100 vessels in 11 families, from animals, fruits and buildings to mazes, letters and numbers. Pick big marbles you could almost count, hundreds of small ones, or a different size every round. Every round is a fresh physics fill, so no two jars ever come out the same.
