Chemtris

Modes and leaderboards

Chemtris is a block-clearing puzzle game for PC, built around connecting colored pieces and setting off chain reactions. It has several ways to play: Arcade gets faster with each level, Lab Expedition is a roguelite run with score quotas and limited pieces, and Adventure adds a choice of three trade-off cards at each new level. Daily Reaction uses one shared seed each day, with unlimited attempts and a leaderboard for your best run.

Online leaderboards cover Arcade, Adventure and each Daily Reaction, with a friends view. Arcade has Normal, Cocktail and Polymer piece options, plus Normal, Hard and Expert difficulty. Cocktail includes some three-block pieces; Polymer uses only three-block pieces. Each Arcade mode and difficulty has its own leaderboard.
