Another amateurish looking game by Bolze, this one is of the time-honored sliding puzzle type. I didn't play it very far, but a reader did, and writes:

"Three of a Perfect Pair, again, is about three girls. After finishing the first puzzle, you can open a file selection. The first three puzzles as well as the title puzzle are safe for work, but after that they, again, turn lesbian. The RIT* files are regular CGs but the OMK* files are black and white sketches."
