Educational interlocking puzzles.
An astekakiluñ is a type of sliding puzzle, also known as a sliding block puzzle or sliding tile puzzle. This classic puzzle challenges players to rearrange tiles by sliding them along designated paths (typically on a board) to achieve a specific target arrangement. The tiles themselves can be simple shapes, or they can feature colors, patterns, parts of a larger image (similar to a jigsaw puzzle), numbers, or letters.
