🧱 滚方块Roll the Block
在线滚方块益智游戏：一块 1×1×2 的长方块在悬空的砖块上翻滚，每滚一步会在“竖立”和“躺倒”之间变化。你要找到路线，让方块正好竖立着落进黑色的洞里。任何一部分悬空就会掉下去，橙色易碎砖还承受不了竖立的方块。12 个关卡由易到难，每关都标出最少步数。Roll the Block online: a 1×1×2 block tumbles across floating tiles, switching between standing up and lying down with every roll. Find the route that drops it standing upright into the black hole. If any part hangs over the edge it falls, and orange fragile tiles can't hold the block standing up. Twelve levels from easy to hard, each showing the minimum number of moves.
方向键 / WASD、在棋盘上滑动或点下方方向键滚动方块。Z 撤回，R 重来。绿色框是起点。Roll with the arrow keys / WASD, a swipe on the board or the arrow pad. Z undoes, R restarts. The green outline marks the start.
玩法说明与常见问题How to play & FAQ
「滚方块」怎么玩？How do I play Roll the Block?
方块竖立时向任一方向滚动会躺倒占两格；躺倒时沿长边方向滚会重新竖立，沿短边方向滚则继续躺着平移一格。目标是让方块竖立在洞口上。多想几步：有时需要先绕远路调整方块的朝向，才能在洞口正好立起来。A standing block that rolls lies down across two tiles; a lying block rolled along its length stands back up, while rolling it sideways keeps it lying and shifts it one tile. The goal is to stand it upright on the hole. Think ahead — sometimes you must take a detour just to get the block facing the right way.
每关的“最少步数”是怎么来的？Where does the minimum move count come from?
每个关卡都用电脑穷举搜索验证过一定有解，并算出了最少需要几步。用最少步数过关可以挑战一下自己。Every level was checked by an exhaustive computer search, which proves it is solvable and finds the fewest moves needed — try to match it.
掉下去了怎么办？What if the block falls?
点“撤回一步”回到掉落前，或者重来本关。撤回会计入步数。Use Undo to step back to before the fall, or restart the level. Undo still counts as a move.
