Target Operation

Combine the numbers. Hit the target.

Target Operation is a mental math puzzle with nothing in the way: a handful of numbers on the table, a target up top, and four operations to connect them. Tap two cards, pick + − × or ÷, and they merge into the result. You win when a single card is left — worth exactly the target.

No remainders, no negative numbers. Just thinking.

Rules you understand in thirty seconds. Targets you think about all day.

▍ STREAK — THE MAIN MODE

One target after another, with every level's points stacking onto your score. Difficulty climbs every three wins: more numbers on the table, bigger targets, fewer obvious paths. The run only ends when you miss — and that is when you find out how far you got.

At the end, one tap builds a card with your score and the levels you cleared, ready to challenge anyone you like.

▍ FOUR MORE MODES

• EXACT TARGET — No rush, no clock. Just you and the target.
• BEAT THE CLOCK — The same challenge, with time running. 90 to 240 seconds, depending on difficulty.
• CLOSEST — Missed the exact target? Get as close as you can: here the distance scores too.
• DAILY CHALLENGE — The same puzzle for everyone, every day. Come back tomorrow and keep your day streak alive.

▍ FOUR DIFFICULTIES

From Easy, with 3 numbers and targets up to 120, to Insane, with 6 numbers and targets past 2,000. Every puzzle is generated with a guaranteed solution — if you did not find the path, it was still there.

▍ SCORING IN THE OPEN

No number that appears out of nowhere when the round ends. The results screen shows the whole calculation: the difficulty base, the speed bonus, the bonus for finishing with no misses and no hints, and what every rejected move and every hint cost you. You learn to score better just by reading it.

▍ 17 ACHIEVEMENTS

Across five categories — Daily Challenge, win streaks, games played, perfection and difficulty. From winning on Hard to closing 30 days in a row, by way of 20 wins without a single hint.

▍ STATS THAT MEAN SOMETHING

Your record and where you set it, win rate, time played, fastest win, hints used, best streak, and a separate breakdown for each difficulty.

▍ STUCK? ASK FOR A HINT

The game solves the puzzle alongside you. Hints come in three levels — which operation is part of the solution, which calculation to start from, which number you need to build along the way — and it tells you when the path to the target is already lost, so you can undo in time.
