From the README

Five original gem and stone puzzle games for JavaScript and TypeScript.

Falling Triplets, Colour Chains, Stone Collapse and Gem Swap: each an immutable, seeded rules engine that runs anywhere, with graded challenges and lessons, saves that replay to the same board, and a keyboard, keypad and touch player in the demo. Magnetic Blocks adds bonded squares, a magnetic floor and its own campaign. Shizen and Arashi each add a separate Colour Chains campaign. In English and Japanese. No dependencies.
