All Fives Domino Score Calculator (Muggins / Znif)
All Fives domino scoring made simple.
Enter the open-end pip values and see whether your move scores points (Muggins, Five-Up, and Znif rules).
The basic scoring rule. All Fives (also called Muggins, Five-Up, or Znif in Israel) scores when the open ends of the chain add up to a multiple of 5. Sum the pip values at every open end after your move. If the total is 5, 10, 15, 20, or 25, you score that number. If it is anything else, you score zero for that turn.
Doubles count their full pip value. A double-five played at the end of the chain shows 10 pips facing out, not 5. This is the most common source of mistakes for new players.
Spinner doubles complicate the count. The first double placed in the chain often becomes a “spinner” — tiles can branch off all four sides. Once that happens, the chain has up to four open ends to sum, not two. Some house rules only allow branching after the spinner is played, others require it immediately.
Worked example. You play 4-2 next to a 4-3 already on the board. The open ends are now 2 and 3. Sum = 5. Score = 5 points. Now your opponent plays 5-3 next to your 2. Ends are 5 and 3. Sum = 8. Score = 0.
Why a quick scorer helps. During fast play, valid scores get missed all the time. Muggins variants let opponents shout “Muggins!” and steal forgotten points, which is exactly why having a scorer in front of you matters.

About target totals. First to 100, 150, or 250 is the usual win condition, depending on house rules. The target is a separate decision from the per-move scoring rule above.
