On your turn, draw a tile and discard one. Build four groups and a pair: a group is three consecutive numbers of the same suit, three identical tiles, or a declared Kong of four identical tiles.
Chi takes a discard to make a sequence; Peng makes a triplet; Gang makes a Kong; Hu declares a winning hand. Only legal actions appear. Concealed Gang uses four matching tiles in your own hand; it does not take the previous discard. You may discard instead. Double-click a tile to discard; press Up Arrow to Pass when a claim is offered. After you discard or Pass, the next AI action happens automatically after a short pause. AI finishes its follow-up action after Peng, Chi or Gang automatically. For later AI turns, press Proceed or Left Arrow. After Leo discards, the game always waits for you: claim or Pass, or press Proceed / Space / Left Arrow when no claim is available to draw and begin your turn. Keyboard: Left/Right selects a tile on your turn; Down clears selection. Space proceeds while waiting or starts the next hand after a result. Enter discards a selected tile, proceeds when no claim decision is needed, or starts the next hand after a result. P Peng, G Gang, C Chi, W Hu / Win, H Hint. When several choices are available, use arrow keys and Enter, or click a choice; Escape cancels. On phones, tap an opponent to inspect their exposed groups.

谜题完成
Well done!
做得好，你完成了彩球分类！
已填格子: 0
太棒了！
玩法说明
填色后会出现一幅图案。每行左边和每列上方的数字，按顺序表示连续填色的格子组。例如“1 2”表示先填一格，至少空一格，再连续填两格。“0”表示整行或整列都为空。
用“填色”标出图案格子，用“标空（×）”标出确定的空格，用“擦除”移除标记。点击或拖动都可绘图，再次点击已有的填色或叉号会清除它。每次拖动会使用同一种标记；“撤销”可恢复整笔操作。电脑上也可以用鼠标右键标空。
绿色线索表示填色分组已符合要求；红色线索表示当前标记无法满足该行或该列的线索，需要重新检查。提示会描出可由线索推导的格子，或指出错误标记，并在“我的记录”中计为使用了辅助。
每道谜题都已验证只有一个解，可以仅靠行列逻辑推导完成，无需猜测。正确填出所有图案格子即可获胜，其余空格不必全部标叉。完成后才会揭晓图案名称。
没有计时或错误惩罚。键盘方向键可移动位置，Enter 或空格键使用所选工具，Escape 取消当前笔画或提示。谜题、撤销历史和完成记录都保存在此浏览器。
每日谜题：所有玩家在同一 UTC 日期获得相同图案，5 × 5 与 10 × 10 交替出现。每日 UTC 零点更新，点击“每日谜题”即可打开。每日与练习的标记在此设备上分开保存。“分享谜题”会复制链接，不会透露图案或答案，无需账号，也不要求连续签到。
玩法说明
滑动图案至相邻位置，或依次点击两个相邻图案，将其交换。让三个或更多相同图案横向或纵向连成一线即可消除，不能斜着交换。
图案消除后，上方图案落下，新图案从顶部补入。若形成新的一线，会继续连消。每个消除的图案得 10 分，再乘以本步的连消次数；交叉处的图案只计一次。
在步数用完前达到目标分数。只有有效交换才扣一步；彩虹交换也消耗一步。没有可行交换时，棋盘会免费重排。没有计时、生命限制或等待时间。
四个相同图案连成直线会留下条纹：横向条纹消除整行，纵向条纹消除整列。五个或更多连成直线会留下彩虹图案。将彩虹与相邻图案交换，可清除棋盘上所有该类图案；交换两个彩虹可清空棋盘。条纹消除会触发沿途其他条纹；若击中彩虹，它会清除数量最多的一类图案。只有实际消除的图案计分。旧存档保留原规则，点击“新棋盘”即可使用彩虹。
在“图案”中选择形状、水果、花朵或数字，仅改变外观，不影响当前游戏。浏览器会记住你的选择。
每局根据难度从图案库中选取 4–7 种图案。继续或重试时保持相同图案；切换“图案”只改变外观。
可选入门（7×7，4 种）、简单（8×8，5 种）、普通（8×8，6 种）、困难（8×8，7 种）或专家（9×9，7 种）。提示会标记本局为使用过提示，不保证获胜。重试保留相同棋盘，新棋盘生成不同布局。
键盘：用 Tab 进入棋盘，方向键移动，Enter 或空格选择相邻图案，Esc 取消选择。棋盘和个人记录保存在此浏览器中。
✓ Well done!
You found every word.
How to play
Find every listed word in the letter grid. Swipe from its first letter to its last, or tap the two endpoints. You can select a word in either direction.
Easy uses words placed across and down. Standard and Challenge also include diagonal and backward words. Each word follows a straight line; words may share letters. Found words stay marked in the grid and crossed off the list.
Hint marks the first letter of an unfound word. Using it marks this puzzle as assisted in My Progress. There is no timer or penalty for a wrong selection.
Daily puzzle: everyone gets the same 10 × 10 board for a date, with a rotating theme. A new puzzle arrives at midnight UTC. Daily, regular and shared-puzzle progress are saved separately on this device. Share copies a link to any puzzle without the answers; close the link with Close or Escape. No account or streak is required.
Keyboard: Tab to the grid, use arrow keys to move, and Enter or Space to choose each endpoint. Escape clears a selection. Your puzzle and results are saved in this browser on this device.
✓ 做得好！
你清空了所有牌。
玩法说明
点击两张相同且可移动的牌即可移除。上方没有牌，且左右至少一侧空着的牌可以移动。亮色牌可配对，暗色牌暂时被挡住。
清空所有牌即可获胜。这是单人配对游戏，不需要了解四人麻将的规则。
每副新牌都经过验证，存在解法；但选择不同的配对可能导致无牌可配。“撤销”恢复上一次配对或重排；“提示”标出一组可配对的牌，不保证后续一定能清空。
“重排”会在当前位置允许的情况下，为剩余牌重新安排一个已验证可解的牌面。若剩余牌堆无法清空，请先撤销一次配对。使用提示或重排后，“我的进度”会将本局标为使用辅助；撤销不会取消此标记。
没有计时限制。牌局和胜局记录保存在此浏览器。键盘操作：用 Tab 切换到牌，按 Enter 选中；按 Esc 取消选择。鼠标悬停或键盘聚焦可查看牌名。
每日牌局：同一 UTC 日期的玩家获得相同、已验证可解的牌面，花园、露台和桥梁三种布局每日轮换。UTC 零点后点击“每日牌局”可打开当天新牌，已打开的牌局不会自动切换。每日、普通和分享牌局分别保存进度。“分享”只分享初始牌面，不包含你的操作或答案；点击“关闭”或按 Esc 可收起链接。不需要账号，也没有连续打卡要求。
Draw one card, or select a card and tap its destination.
How to play
Tap the stock to draw one card. When it is empty, tap it again to recycle the waste. You have unlimited passes and no timer.
Build the seven columns downward in alternating colors: a red 7 goes on a black 8. Move a face-up card or a complete descending stack. Only a King can fill an empty column. Uncovering a face-down card turns it over automatically.
Build the four foundations from Ace to King, each in its own suit. A single card from a foundation may move back to a column if needed.
Tap a card, then tap its destination, or drag a card or stack. Keyboard: use Tab and Enter to select cards and destinations; Escape clears your selection. Undo reverses the last action, including draws and recycling.
Hints suggest a possible move, not a guaranteed solution. Auto-finish becomes available when stock and waste are empty and all remaining cards are face up. Hint or auto-finish marks that deal as assisted in My Progress. Not every shuffled deal can be won.
Your deal and wins stay saved in this browser on this device. No registration needed.
Swipe the board or use the arrow keys.
How to play
Swipe in any direction, use your keyboard’s arrow keys, or tap the arrow buttons. All tiles slide together. Matching numbers combine into one tile: 2 + 2 makes 4, then 4 + 4 makes 8.
Each slide that changes the board adds a new 2 or 4 tile. A tile can merge once per slide. Your score increases by the value of each merged tile.
Reach 2048 to win, then keep playing if you like. The round ends when the full board has no matching neighbors. No timer or registration. Your board and personal best are saved on this device.
Choose a piece, then tap its top-left position on the board.
How to play and score
Tap a piece, then tap the board where its top-left corner should go. You can also drag a piece onto the board. A preview shows whether it fits. Pieces keep their orientation.
Fill any row or column to clear it. Use all three pieces to receive a fresh set. Play ends when none of the remaining pieces fits. There is no timer.
Each block placed earns 1 point. Each cleared row or column earns 10 points, plus 5 extra for each additional line cleared in the same move. Best scores and the current game save on this device.
Keyboard: Tab to choose a piece or enter the board. Use arrow keys to move between cells and Enter or Space to place. Escape clears your selection.
彩球分类挑战
利用同色移动规则与两个空管，规划每一步。
将顶部同色球组移入空管，或移到顶部同色且空间足够的球管。利用两个空球管作为缓冲，把每种颜色分别集中到各自的球管。
可选择 5 × 5 至 11 × 11 棋盘。单人解题、在同一题中挑战 Marcus，或观看两位 AI 寻找解法。可以撤销重新思考，没有倒计时。
例如，顶部的红色球组可以移入空缓冲道或移到红色球上，但不能移到蓝色球上。每次转移尽可能多、且能容纳的顶部同色球。腾空一条球道可能有帮助，但过早填满两个缓冲道会减少合法选择。
尝试露出被压住的颜色，同时保留一个有用的落点。完成一条单色球道能简化局面，但使用最后一个缓冲道前先看看下一步。“重新开始”回到初始排列。“分享谜题”让朋友尝试同一起始棋盘，不会透露你的路线；各自的本地进度互不影响。
