玩法说明与常见问题How to play & FAQ
「俄罗斯方块」怎么玩？How do I play Falling Blocks?
移动和旋转不断落下的方块，把一整行填满就会消除得分。一次消 1/2/3/4 行分别得 100/300/500/800 分（乘以等级），每消 10 行升一级、下落更快。方块堆到顶部游戏结束。Move and rotate the falling pieces to fill complete rows, which then clear. Clearing 1/2/3/4 lines at once scores 100/300/500/800 × level; every 10 lines raises the level and the speed. The game ends when the stack reaches the top.
「暂存」有什么用？What does Hold do?
按 C 或 Shift 可以把当前方块存起来留到更合适的时候用，每个方块落地前只能暂存一次。Press C or Shift to put the current piece aside for later; you can hold once per piece.
方块出现的顺序是随机的吗？Is the piece order random?
采用「7 种一袋」的随机方式：每 7 个方块里 7 种形状各出现一次，既随机又不会长时间等不到长条。It uses a 7-bag: each group of seven contains every shape once, so it stays random without long droughts.
这是官方的俄罗斯方块吗？Is this the official Tetris?
