Why We Added Traditional Chinese

Tui, our co-creator, is half-Taiwanese and learning to read and write Traditional Chinese. Translating Rigid Digit into her mother-tongue means she can share the game and play against her cousins and friends back in Taiwan. Switch to it any time from the Language setting.

Maths crosses language barriers beautifully, and we'd love to localise Rigid Digit into more languages to reach an even wider audience. If there's a language you think we should add, tell us in the comments below.

A Rigid Digit result in Traditional Chinese and Dark Mode: the winning tile 99×5 = 495, four green squares and a flame, with 10 秒內完成! (done in under 10 seconds), 4 equations in 0:06 — A solve in Traditional Chinese (and Dark Mode): 4 equations, 6 seconds, and a flame.
