Lethal is a free daily browser game where you win in one turn — a logic puzzle in the form of a strategy card game.
If you like games like Wordle or Slay the Spire, it fits right between them. No randomness. No downloads. Just one enemy, one hand of cards, and one clean solution.


Why I Made It
Most strategy card games take time. Most digital card games are deckbuilders. I love those genres. But I wanted a fast format, a brain teaser puzzle you can solve in a few minutes, but still feel clever doing it.
Lethal gives you that "perfect turn" feeling you get from the end of a long play through of Slay the Spire, but in a smaller daily logic puzzle. It runs in your browser, no sign-up needed, so you can get to the puzzle immediately whenever you want and wherever you are. You play over 30+ puzzles right now, which means 30+ enemies to beat!
A few of the enemies you'll face:
Designed to Be Solved
Every puzzle is hand-built and tested by different puzzle authors. You're given all cards up front and it’s your job to figure out the right sequence to win.
If you like free, constant puzzles that test strategy and reward careful planning, this is the game for you.
