Adults only

The Edu Casino is for adults (18+). It uses fictional chips only — no real money, nothing to buy, nothing to win.

Craps Probability Lab

Roll two dice as often as you like and watch the totals build the 2-to-12 curve against the exact expectation. Then answer questions about the dice and the bets, and choose twice at the table: a bet, or sitting out.

How to play

Roll. One roll, 10 or 100: the bars grow next to the exact expected counts.
Answer. Six questions on totals, points and house edges.
At the table. Twice, bet 10 fictional chips or sit out. The lowest edge or sitting out is wise.
Score. 100 per right answer and per wise choice. Chips won don't count.

Quick tips

7 is king. Six of the 36 rolls make 7, the most common total.
6 and 8 are twins. Both have five ways to come up. The curve is symmetrical.
Point races are simple. Only the point and 7 matter: a point of 6 wins 5 times out of 11.
Big payouts, big edges. Any seven pays 4 to 1 for a 1-in-6 chance and keeps 16.67%.
Pass line is the least bad. On this table it keeps 1.41%, the lowest edge. Sitting out keeps nothing.
