How each game works

Kasumi Puzzle

Turn it until it becomes a picture ・ 2–10 min ・ 12 puzzles

  1. Swipe left or right to rotate the lines
  2. At exactly one angle, the lines connect into a picture
  3. The color changes as you get close, and it snaps into place when you are right
  4. Solve all 12 to finish. The next round starts from different angles

Keyboard: ←→ rotate / hold Shift to rotate faster / R restart

Wakeru Puzzle

Cut it exactly right ・ 1–5 min ・ 5 shapes per set

  1. The target ratio (1:1, 1:2 and so on) is shown at the top
  2. Swipe across the shape to cut it along that line
  3. Right after the cut, your error is shown, like "1.8% off"
  4. A set is 5 shapes. The lower your average error, the better

Keyboard: ←→ line angle / ↑↓ line position / Enter cut / R retry

Hikari Puzzle

Connect the light ・ 3–10 min ・ 8 stages

  1. Light leaves the source and bounces off the mirrors
  2. Grab a mirror and move your finger; the mirror turns to face it
  3. Clear the stage when the light reaches the target
  4. Connect all 8 stages to finish. Fewer moves is better

Keyboard: ↑↓ select mirror / ←→ rotate / hold Shift to rotate faster / R restart

Sukima Reflex

Slip it through the gap ・ 1–5 min ・ 3 misses per run, personal best

  1. The bar slides left and right. Tap anywhere to stop it where it is
  2. If the bar fits inside the gap, it goes through. Each success narrows the gap
  3. A miss stays on the wall, so you can see how far off you were
  4. Three misses ends the run. Your count is saved as a personal best

Keyboard: Space or Enter to stop / R to start over

FAQ

Is it free?

Yes. Every game is free and there is no sign-up.

Do I need to install anything?

No. Open the page in your browser and play. It works on phones, tablets and computers.

Is my progress saved?

Only your personal best and your sound setting are saved, inside your own browser (localStorage). Nothing is sent to a server. Progress within a set is not saved, so reloading the page takes you back to the first puzzle.

Do you collect personal data?

We do not collect anything that identifies you, such as your name or email address. There are no logins and no forms. To improve the site, we measure page views and similar traffic with Google Analytics, which uses cookies.

I cannot hear any sound

Browsers keep sound off until you first touch the screen. If it is still silent, check that the speaker button at the top right is not muted.

Can I play with just a keyboard?

Yes. Every game can be played with the arrow keys and Enter, and R restarts. Controls differ per game, so check the "?" button in each game.

Is there a Japanese version?

Yes. Use the "JA" link at the top right to switch.

Will there be new games?

Yes, we add them one at a time. New ones are marked "NEW" on the list.
