Confirm that the game is blocked
A blocked ending requires two consecutive passes. After the first pass, the other player may still place a tile and change an open end. A placement breaks the sequence of passes. Check both exposed numbers before concluding that neither player can continue.
In Block mode, a player with no matching tile passes, leaving the stock untouched. In Draw mode, that player must draw while the stock contains tiles and no placement is available. A pass becomes legal only when the stock is empty and the hand still has no match. Both modes use the same remaining-pip comparison once consecutive passes end the game.
The three worked endings below use Block mode. We reveal both hands to explain the results. During play, you see your own tiles and your opponent's tile count; you cannot read their tile values from that count.
Add both halves of every remaining tile
Add the two values on each tile, then add those tile totals together. A 4–4 contributes 4 + 4 = 8 pips. A 0–1 contributes 1, and a 1–1 contributes 2. The blank half contributes zero, so 0–0 contributes zero too. Doubles count both halves normally.
Use only tiles still held by the player. Tiles already placed on the chain do not enter this comparison, and unused stock is not assigned to either player. The lower remaining total wins a blocked game. Equal totals produce a draw, even if the players hold different numbers of tiles. These totals determine the result of this game; do not treat the difference as a separate reward or a promised score across multiple games.
Follow a one-tile loss, move by move
Consider a late position with 6 exposed on the left and 3 on the right. White holds 4–4 and 2–3. Black holds 0–1, 1–1 and 2–2. It is White's turn, and fourteen undealt tiles remain in the stock. These are all the tiles still in the players' hands.
White places 2–3 on the right, matching its 3 to the exposed 3. The new right end is 2, so the ends now show 6 and 2. Black places 2–2 on that right end. The double leaves the exposed value at 2. White now has only 4–4, while Black has 0–1 and 1–1.
White cannot match either 6 or 2 and passes. Black also has no 6 or 2 and passes. The second consecutive pass ends the game. White's single tile totals 8 pips; Black's two tiles total 1 + 2 = 3. Black wins because 3 is lower than 8. The unused stock stays outside the comparison.
| Remaining hand | Tiles held | Pip total |
|---|---|---|
| White: 1 tile | 4–4 | 4 + 4 = 8 |
| Black: 2 tiles | 0–1; 1–1 | 1 + 2 = 3 |
Equal pips make a draw
Take a separate position with open ends 4 and 5, just after Black has placed 4–4 on the left. White holds 1–2 and 0–6. Black holds only 3–6. White cannot match either end and passes; Black cannot match either end and passes too.
White's two tiles total (1 + 2) + (0 + 6) = 9. Black's single tile totals 3 + 6 = 9. The blocked result is a draw. Having fewer tiles does not break the tie, and neither does being the player who placed the last tile on the chain.
| Remaining hand | Tiles held | Pip total |
|---|---|---|
| White: 2 tiles | 1–2; 0–6 | 3 + 6 = 9 |
| Black: 1 tile | 3–6 | 3 + 6 = 9 |
An empty hand wins immediately
A zero-pip hand and an empty hand are different. A player still holding 0–0 has a tile left to play. Playing your last tile wins immediately, so the game does not wait for passes and then compare two zero totals.
In a third position, the ends show 1 on the left and 0 on the right. White has only 2–2; Black has 0–0 and 0–2. White cannot play and passes. Black chooses to place 0–2 on the right, joining its 0 to the chain and exposing 2. This placement breaks the pass sequence and gives White a match.
White now places 2–2 on the right and empties the hand. White wins immediately, even though Black's remaining 0–0 has zero pips. This is one legal sequence, not a forced choice for Black: Black could instead have placed 0–0 on the exposed 0. The example shows why you must read the new ends after a placement and distinguish a blocked result from a final-tile win.
Use the count without guessing hidden tiles
When a game is close to blocking, count your own remaining pips as well as your tiles. Removing a heavy tile can reduce the total you would carry into a blocked ending. But a matching opportunity and the new exposed numbers still matter: the third example shows how a placement can give the opponent an immediate finish.
An opponent's pass tells you they lacked a match for the ends at that moment. It does not reveal their pip total. You therefore cannot assume that blocking an opponent with more tiles will win. The first example proves how a larger hand can have the lower total; the second shows that equal totals can hide behind different hand sizes.
Before judging an ending, ask whether someone has emptied their hand, whether the passes were consecutive, and what each remaining tile contributes. Count doubles twice, blanks as zero, and leave the chain and unused stock out of the hand total.
Practise reading the open ends
The guided demo below follows 4–4, then 1–4, then 1–1. It teaches matching and exposed ends; it does not replay the three endings above. Watch how the last double keeps that end at 1, just as 2–2 kept an end at 2 in the first example.
