I vaguely recall playing a computer game in the early days of computers that consisted of arranging tiles back and forth within a nonmoveable frame in order to work a single one of the tile out from all the others, I can’t remember what it was called.
The tile which was to be removed often looked impossible to remove because of the presence of all the other tiles around it, but by moving the tiles this way and that, the to-be-removed one could be removed.
If you’re just looking for similar games, do a google search for “sliding tile game”.
They’re pretty common, my mom had a plastic one back when she was a kid.
If you’re looking for a specific game, sorry I’d need more information. Was that the entire game, a sliding tile puzzle? Or was this just a mini game within a larger game? What was it about?
It wasn’t that “Fifteen Tile” puzzle that consists of a square with slidable tiles embedded within, numbered from 1 to 15. What I’m thinking of is along the lines of the “Gridlock” game suggested by E. Darwin, but the one I’m thinking of was more elaborate than that–at the more difficult levels, there were dozens of intervening blocks or tiles that had to be arranged out of the way to get the target tile out. Gosh, the name is on the tip of my tongue…
