How to play Luck Lab

Choose coins or two dice and press a button to run 1, 100 or 10,000 trials. The bars show how often each result came up. With few trials the picture is lumpy; with many it settles close to the expected odds.

About this toy

Luck Lab is a free browser toy in our Sandbox collection. It is a sandbox: there is nothing to win or lose, so experiment freely and see what happens. It runs on phones, tablets and computers, needs no app, and has no in-game purchases.
