Hey Product Hunt! 👋
I'm the solo dev behind Larss, a 1v1 competitive block-blast
strategy game that's been about a year in the making.
Quick backstory: I loved Block Blast but wanted a version
where skill actually decided the outcome, not just how many
combos you could chain solo. So I built one where two players
share the same board, alternating turns placing tetromino
pieces. Fill rows, columns, or diagonals to clear and score.
No dice, no RNG, pure positional play.
What makes it different:
🎯 99% deterministic (skill wins, not luck)
♟️ Chess.com-inspired ranking (Bronze → Elite leagues)
👀 Watch top games live via "Larss TV"
🎮 Free, browser-based, no download
🤖 5 AI opponents at various skill levels
👥 Ranked/unranked matchmaking + friend games
I've been iterating based on player feedback for months.
Recently overhauled the tutorial to get you into a match
in ~2 minutes, and just added the ranked leagues system.
Would love your feedback! Whether it's about:
- The core mechanic
- Onboarding experience
- What could make this stickier
- Or just what you thought when you played
I'll be here all day answering questions. Play at larss.io
Thanks for checking it out!
The concept of surrounding your opponent on a shared board sounds really clever and I love that there's no install needed. One thing I'd love to see is a quick practice mode against a basic AI opponent, so newer players can warm up and learn the surrounding mechanic before jumping straight into 1v1 matches.
Tetris meets Go is a pretty wild combo but honestly it works really well. the shared board idea makes you think way more defensively than a normal block game, and clearing lines right before your opponent almost fills a row is so satisfying.
the shared board twist on tetromino placement is such a smart idea, the spatial pressure of trying to box in your opponent while managing your own lines adds so much tension to every move
