The catalog in 3D
The same catalog has a room you can walk around in. The cat behind the counter is the AI Catbot, and they pick real games from it when you tell them what you feel like playing. Nothing is for sale, here or in there. Go in from here and this game is already out on the counter, with more like it waiting on the shelf next to it.
How it feels
A calm, methodical number puzzle where you flip and balance digits to match totals, feeling clear-headed and satisfyingly logical.

What players say
Players describe FlipSum as a clean, minimalist logic puzzle akin to Sudoku with a number-flipping twist. Many praise its relaxing music and infinite puzzles, but consistently note missing quality-of-life features like an exit button and slow screen transitions.
