Quantris is coming to Steam Early Access
Quantum Native
Quantris is a falling-block puzzle game where the blocks follow quantum mechanics, and it's coming to Steam in Early Access. I'll post the date here once it's set.
How it plays
A Hadamard block puts the piece it touches into superposition: it might be there and it might not. Pieces that share a gate become entangled, so their outcomes are tied together. Nothing is settled until you drop an observation block. Then every entangled piece collapses at once, and you find out which blocks stay.
A line clears only when every block in it has been measured and they all came out the same way: all there, or all gone. Plan for the collapse, or get buried by it.
The quantum state is simulated with the same math a quantum computer runs, so the odds are real quantum probabilities. You don't need any physics to play. Each mode teaches its rules as you go.
What's in Early Access
- Six single-player modes: Marathon, Sprint, Ultra, Flux, Puzzle Vault and VS AI.
- Co-op and head-to-head for two players on one machine. In co-op, two towers share one team score and entanglement reaches across both boards. In head-to-head, your measurement can knock blocks out of your rival's tower.
- The same two modes online, with a friend by room code or anyone from the public room list.
- Leaderboards for each mode, and a replay of every run, online matches included.
- Full controller support with remappable buttons and keys, and handling you can tune: DAS, ARR, DCD, soft drop speed and lock delay.
Why Early Access
A lot of Quantris came from players in our Discord, and I owe the early ones a big thank you. Quantum mechanics leaves more room than I can design for on my own: new gates, new ways to tie two boards together, new modes. I want Steam players helping decide where it goes while the game is still evolving. And the multiplayer modes need a lot more testing than a small group can give them. I'll post what changed here with each update.
Wishlist it and Steam will let you know when it's out. Questions, bugs and ideas are welcome in the discussions, or on Discord
