The AI scores every legal cell across all four axes, all nine windows per axis, then plays the best. It takes a four to win and blocks a four you have made.

Claim a line, close a box and keep the turn. Best of three rounds; score nothing in a round and you lose it on the spot.

The rival throws a fixed printed sequence, so read the next throw and answer it. Nothing here is luck - keys 1 / 2 / 3 also work.

Hit, stand, double, split and insure against a dealer who stands on 17.

The patience classic: four free cells, undo and one-click auto finish.

Endless three-lane runner: switch lanes, jump crates and slide under beams.

Thirty seconds of whack-a-mole. Fast hits build a combo multiplier.

Pull back, aim and launch. Topple the three marked blocks in six shots.

Drop the sliding block and stack it clean. Perfect cuts keep full width.
