Dominoes
Dominoes is a tile-matching game for two players. On KachaPlay (kachaplay.com) we play the Block game with a classic double-six set — free in your browser, against the computer, a random opponent, or a friend. This page covers the exact rules we use, the ways to play, and a few tips.
The rules we use
- A double-six set has 28 tiles. Each player is dealt 7 tiles; the other 14 are set aside and unused — there is no boneyard and no drawing.
- Seat one opens with any tile. Players then take turns adding a tile to an open end of the chain, matching pip values.
- A player who cannot play must pass.
- The first player to empty their hand wins the round.
- If the game is blocked — neither player can add a tile — the player with the lower pip total in hand wins. Equal totals are a genuine draw.
Dominoes is the one game here with hidden information: you always see your own hand and how many tiles your opponent holds, but never which tiles they are. The deal is shuffled by the server, so the tiles you get are not something either side can arrange.
Ways to play on KachaPlay
Against the computer
Three difficulty levels — Rookie, Sensei and Master. Computer games are for practice: no rating change, no coins or gems.
Online against a random opponent
Get matched with another player. These games are rated — dominoes keeps its own Elo rating, and online games are where coins and gems come from.
Against a friend
Create a room and share the link, or invite a friend. Friend rooms are casual (no rating). Each online game can be no time limit, 5 minutes or 10 minutes per side. See How to Play for the full rating and currency rules.
A few tips
- Play your heavy tiles early — if the game blocks, a big hand loses on pip count.
- Watch which numbers your opponent passes on; those are the ends to keep alive.
- Holding a double can let you match an end no single tile of yours can.
- Since there is no drawing, count what has been played to guess what they still hold.

多米诺（中文）
多米诺是双人骨牌接龙游戏。在 KachaPlay（kachaplay.com）我们采用 Block（封锁）玩法，使用经典双六牌组——打开浏览器即可免费对战：可选电脑、随机对手或好友。 本节说明我们采用的具体规则、对战方式与几点建议。
我们采用的规则
- 双六牌组共 28 张。每人发 7 张；其余 14 张搁置不用——没有牌堆、不能补牌。
- 先手可打出任意一张。此后轮流在骨牌链的开放端接牌，点数须匹配。
- 无牌可接的一方必须“过”（pass）。
- 先出完手牌的一方赢下该局。
- 若封盘（双方都无法接牌），手牌点数之和较小者获胜； 点数相同则为真正的平局。
多米诺是这里唯一含暗牌信息的游戏：你始终看得到自己的手牌以及对手手牌的数量，但看不到具体是哪些。 发牌由服务端洗牌，任何一方都无法安排自己拿到的牌。

几点建议
- 早点打出大点数的牌——一旦封盘，手上点数大就会按点数判负。
- 留意对手在哪些点数上“过牌”，尽量保住这些开放端。
- 手握双牌有时能接上单牌接不了的端口。
- 由于不能补牌，数一数已打出的牌，推断对手可能还剩什么。
常见问题
这是哪种多米诺？使用双六牌组的 Block 玩法——没有牌堆，接不上就“过”。
卡住了能补牌吗？不能。Block 玩法没有补牌；接不上开放端就过。
一局会平吗？会——若封盘且双方手牌点数相同，即为平局。
