The goal

Whenever it's the end of your turn and every open end on the board adds up to a multiple of 5, you score that total. First player to the target score wins the match.

Setup

28 tiles are shuffled face down. With 2 players you each draw 7; with 3–4 players you each draw 5. The rest form the boneyard (draw pile). The highest double opens the board.

How to place a tile

Tap a tile in your hand to select it. Every spot on the board where it can legally go lights up as a glowing slot — tap the slot you want and the tile snaps into place. A badge on each slot shows how many points that move would score. Doubles are placed crosswise; non-doubles extend the line.

Your house rule — every double is a spinner

Normally only the first double can be played on all four sides. In this game every double is a four-way spinner — it can be built off all sides, so each open double shows slots on up to four sides. The Open Ends panel below the board summarizes every open end and what it's currently contributing to the total.

Scoring the ends

Add the values of all exposed open ends. A standing (un-built-on) double counts its full value — an open double-five is 10, an open double-six is 12. Once a double has tiles built off it, it stops counting and its branches' ends count instead.
Example: ends showing 3, 0, and an open double-six (12) total 15 → score 15.

Drawing & passing

No legal play? Draw from the boneyard until you can play. If the boneyard is empty and you still can't, you pass.

Muggins

If an opponent makes a scoring play, a Muggins! button appears for a moment — tap it to steal their points. (Your own scores are counted automatically.)

Ending a hand

A hand ends when someone plays their last tile ("chips out") or the game is blocked. The winner adds the pips left in everyone else's hands, rounded to the nearest 5, as a bonus. Then a new hand is dealt until someone reaches the target.
