Arithmetic Line

Click to bend a glowing line through gates that add up to the target sum, dodging wrong numbers before the clock hits zero.

Arithmetic Line drops you onto a grid where a line snakes forward on its own. Your only input is a mouse click, which makes the line veer left or right. The twist: each gate you pass through slaps a number onto your running total. You need that total to hit the target shown at the top. My first runs were disasters. I'd click too early, send the line into a 9 when I needed a 2, and watch my total blow past the goal. But then you start doing quick mental math: target is 15, I've got 8, so I need a 7. There's a 7 on the right, but a 3 on the left, so click now. That split-second calculation while the line zips along is the whole game. It's simple to pick up, but the speed ramps up and the number layouts get trickier. Sometimes the correct number is tucked behind a wrong one, forcing you to take a longer path. I kept coming back because each run is only a minute or two, and the 'just one more try' feeling is strong. It's a brain workout disguised as a twitch reflex game.

Aim for gates that bring you closest to the target, not necessarily the biggest numbers. Click slightly before you reach a turn; the line has a tiny input delay. If you overshoot, don't panic — you can loop around, but watch the timer. Memorize common addition combos so you react faster. In later levels, wrong numbers are placed as bait; scan ahead for the correct path. Use the edges of the screen to buy time if the line's about to hit a wall.
