Sum Circuit
Make Sums. Watch Tiles Fall
Only for iPhone
Free
iPhone
Connect numbers. Plan for what falls next. Explore a 30-stage Journey, a 365-puzzle Expedition, and a fresh Daily Circuit, with Undo and Hint always close at hand.
One connection changes what comes next. Connect 2–4 neighboring number tiles to match the target sum. No diagonals. A correct connection clears those tiles and lets the numbers above fall into place. A tile you clear now might be needed for the next target. Complete the targets from left to right to light the circuit.
• 30-stage Journey: Learn the rules, then explore multiple targets and different connections.
• 365-puzzle Expedition: Unlock circuits one puzzle at a time, complete each sector, and save your best star result. The Play menu shows available puzzles and how to earn stars.
• Daily and Bonus circuits: Solve a date-based puzzle. Complete the Daily Circuit to unlock its bonus for free.
• Consistent controls: Tap tiles and press Connect, or drag and release. Undo, Hint, and Restart stay in the same place on the game screen.
• Hands-on tutorial: Connect tiles, use the numbers that fall, and undo a connection that leaves you stuck. Repeat it without losing your current puzzle.
• Your choice of feedback: Korean, English, and Japanese; sound effects, haptics, and optional background music. Music is off by default.
• Offline play, no account: Puzzles, progress, and completed-stage records are stored on your device.
Watching ads is optional. Journey stages 1–2 have free hints, and every later puzzle includes free hints. After using them, one optional rewarded ad unlocks the remaining hints for that puzzle. Complete the Daily Circuit to unlock its bonus for free, or choose an ad to play the bonus early. If a prepared ad is unavailable or cannot load, the requested feature opens for free. Ads require an internet connection.
