About KOMAINU LAB

KOMAINU LAB ・ lab.koma-inu.co.jp

KOMAINU LAB is a site where we make and publish small games you can play right away in your phone browser. There is nothing to install and no sign-up: open a game and it starts. Games are available in Japanese and English.

What we make

Short games you play with one finger: tap, flick or trace. The themes range from familiar Japanese pastimes and crafts, such as daruma otoshi, goldfish scooping, calligraphy and kintsugi, to little contraptions where gears merge and marbles multiply. The more you play, the more upgrades, collections and ranks you unlock.

Our rules for every game

• Results come from your timing and choices, not from luck.
• No ads until a new player has seen the most satisfying moment of the game.
• Ads appear only at breaks, such as after a round ends, never while you are playing.
• Some games offer a bonus for watching a video, but watching is your choice and you can play without it.
• We make our own art and sound.

How a game gets here

We build new prototypes every week, and only the ones that pass our own playtests are published on this site. After release we keep tuning difficulty and clarity based on how the games are played (we do not collect names or similar details; see the Privacy Policy). We plan to add a few new games each month.

Free to play

Every game is free. In some games, once you have used up the free rounds for the day, you can watch one short video to keep playing. Your progress is saved in your browser on this device and is removed if you clear your browser data.
