All Fives (Muggins) rules

1. 1Use a double-six set. Two to four players, alone or in two teams.
2. 2On your turn, play one tile with a half that matches an open end, touching that end.
3. 3Deal seven tiles each with two players, or five each with three or four. The rest stay face down as the boneyard.
4. 4At many tables the player holding the highest double leads the first hand (some draw for the lead instead). Play goes around the table to the left.
5. 5In later hands, most tables let the player who went out lead, and a blocked hand draws for the lead again. Some tables pass the lead one seat to the left each hand; Pipside does that unless you pick “The winner” in setup.

After you play, add up the pips on all the open ends. If the total is a multiple of five (5, 10, 15, 20 and so on), you score that many points.

The first tile counts too, in every hand. Lead the 5-5 or the 6-4 and you score 10 right away.

• Only the open ends count: the outer half of the last tile at each end. Every double goes crosswise (turned across the line, so both halves face out), so a double on an end counts both halves: the 6-6 counts 12.
• Nothing scores unless the ends make exactly 5, 10, 15, 20 and so on. A count of 13 scores nothing, and nothing carries over to the next play.

Many tables play with a spinner. The first double is the spinner. Tiles go on both of its sides first, then on its top and bottom too, so there can be four open ends to add up. Until both of its sides have a tile, the spinner itself is still an open end and counts both halves: with the 5-5 led and a 3-5 on its left, the ends make 3 + 10 = 13.

In Pagat's All Fives rules, only the first double is the spinner. Later doubles still go crosswise, but tiles go on just their two sides.

Here's a board that adds up to 18. The double-five is the spinner. While one of its sides was empty, the spinner was an open end and counted both halves. Now both sides have tiles, so the spinner itself counts nothing. The top ends in the 6-6, crosswise, so it counts 12. The right ends in a 6 and the left in a blank (0). Nothing is on the bottom yet, so the bottom counts nothing.

1. 1If you can't play, draw from the boneyard until you can. Pass only when it's empty.
2. 2Your last tile scores like any other play. Then, for going out, you also score the pips left in the other hands, rounded to the nearest five. For example, 17 left over scores 15, and 18 scores 20.
3. 3With partners, when either of you goes out, your team scores the pips in the two opponents' hands. Your partner's leftover tiles don't count. Some tables also take your own team's leftover pips off your score.
4. 4If the boneyard is empty and nobody can play, the game is blocked: the player with the fewest pips left in hand scores the others' pips, rounded the same way. With partners, the low team scores only the other team's pips. That's what Pipside does; some tables let the low team take every pip left, its own too (“Lowest hand takes all” in house rules).
5. 5The first player or team to the target wins. Pagat gives 200 for three or four players and 250 for two.
