Deal Or No Deal
Browser take on the game show: keep one of 26 cases, open the rest, and decide each round whether the banker's offer beats it.
Deal or No Deal is the browser adaptation of the television format. Twenty-six cases hold amounts from one cent to a million dollars. You claim one unopened at the start, then open the others in batches, and every value you reveal is a value your own case no longer holds. Between rounds the banker calls with an offer to buy you out.
That is the entire game, and it is pure decision-making under uncertainty. The average of everything left on the board is the honest value of your case, and early offers deliberately sit below it. Late, with two or three big amounts still live, the offers get close to fair and the swings on each case get brutal, which is where the show got its drama from.

Mouse only: click cases to open them, then Deal or No Deal on each offer
Tips
- Average the amounts still on the board. Early offers sit well under it, so No Deal is usually correct.
- Knocking out low values is what actually raises the offer, not how many cases you open.
- Late offers creep up towards the true average, which is the point where dealing stops being a bad trade.
