About the game

Yatzy is the old dice game for one or more players, here as a solo game on the Game Boy. Each turn you roll five dice, then roll again up to two more times, keeping the dice you like between rolls. When you are done rolling, you choose one of the fifteen scoring categories for that hand; each category can be used only once, so the game ends after fifteen turns.

The categories are the singles (ones through sixes), one pair, two pairs, three and four of a kind, the small and large straights, the full house, chance and the five of a kind, which gives the game its name. Scoring at least 63 points in the singles earns a 50-point bonus. The game keeps your high score.

Playing it here

This is a homebrew game made for the Game Boy: a new game by an independent developer, not a commercial release. It runs here in binjgb, a Game Boy emulator compiled to WebAssembly. Click Play now and press Enter on the menu to start.

The high score is kept in this browser, the same way the cartridge's battery memory would keep it. F2 also saves the current state of the emulator and F4 brings it back. A gamepad works too.

A few things worth knowing

Holding dice. Move the cursor to the hold button and press X: a ^ marker appears under the dice. Press X on a die to hold it, and a star shows under the dice you are keeping.

Each category once. A star next to a category means it is already used. After the last roll of a turn you must score somewhere, even if it is a zero.

Go for the bonus. Three of each number in the singles adds up to exactly 63, the amount needed for the 50-point bonus.
