This is a 15 puzzle (also called Gem Puzzle, Boss Puzzle, Game of Fifteen, Mystic Square, Sliding puzzle, etc.) with different levels.
In the first level you should arrange 15 bricks with numbers 1 to 15 in order, as in any traditional 15 puzzle. Then, in the other levels you should arrange bricks with other things than numbers, such as Greek letters.
But of course, if you only want a traditional 15 puzzle you can stay at level 1…
这是一个15拼图(也称为宝石拼图,老板益智,十五,神秘的广场游戏,拼图等),不同的层次。
在第一个层面,你应该安排15砖有数字1到15的顺序,如在任何传统的15谜题。然后,在其他级别,你应该安排砖与其他东西不是数字,如希腊字母。
不过,当然,如果你只想要一个传统的15拼图,你可以停留在1级...
