About this game

One more number. One perfect sum.

SUMLOOP is a number puzzle with a simple idea: trace neighboring numbers and match the target total. Easy to start, with plenty of room to chase a better score.

TRACE. ADD. MATCH.
Connect numbers horizontally, vertically, or diagonally. If the target is 8, try 1 → 6 → 1. Lift your finger when the total matches. Find longer paths and build combos to push your personal best.

TWO WAYS TO PLAY
• Endless: solve each puzzle within 10 seconds. Every correct answer resets the clock to 10 seconds. How long can you keep going?
• Time Attack: make every second count in a 120-second challenge.

Mistakes do not deduct extra time in either mode.

FIND YOUR RHYTHM
Bell sounds, combo effects, and original background music bring each match to life. Adjust music, sound effects, and vibration in Settings.

Enjoy a quick mental warm-up, practice adding numbers, or take another run at your best score. Play at your own pace between challenges, then chase that next perfect sum.

No account registration is needed. The game can be played offline; ads require an internet connection. English and Japanese interface text is included.

Your next great match is at your fingertips.
Trace, add, and match! Chase combos in Endless and 120-second Time Attack.
