Tetris meets crosswords

Hey Indie Hackers! 👋

This week I launched Sevenfold, my first puzzle game. Each day, you try to fit 7 Tetris-like blocks into a unique grid, with three difficulty levels. Solve them fast enough and you might make it onto the daily leaderboard.

The puzzles are generated by a Rust algorithm I built that explores millions of combinations, only keeping puzzles with exactly one solution. It analyzes placement options and forced moves which I use to determine each puzzle’s difficulty.

Would love to hear some feedback on the gameplay and the app itself.
