Arithmetic Line 2021

Can you trace a path that adds up perfectly? Arithmetic Line 2021 turns quick mental math into a fast-line drawing test with zero room for sloppy sums.

Arithmetic Line 2021 keeps things simple: a grid of numbers sits in front of you, and a target value flashes up top. Your job is to drag a line through a chain of digits so every operation along the path equals that target. Sometimes it's pure addition, sometimes you'll hit subtraction or multiplication tiles that flip the whole route on its head. I liked the tension that builds when you've drawn half a path, realize you're two points over, and have to backtrack while the timer chews away. What got me coming back was the split between planning and improvisation. The early levels let you stop and count on your fingers, but once the target gets into the 50s or negatives pop up, you're scanning the board for shortcuts like a human abacus. The line itself has a nice little snap effect when you connect valid numbers — you'll feel the difference between a smooth solve and a clumsy miss. Keyboard controls help too: arrow keys nudge your path when the mouse gets jittery. You won't find fancy graphics or a story here. It's a bare-bones math sprint that respects your time and punishes wishful thinking. If you enjoy brainteasers like Sudoku but want something more physical, this scratches that itch. Just watch out for the mirrored boards in later stages — they'll flip your whole spatial logic sideways.

Use Mouse To Play and Keyboard

Work backwards from the target number to spot quick addition chains before you draw. Use the keyboard arrow keys for small precision moves when the mouse line overshoots. Memorize where negative and multiplication tiles sit on the board early — they change your path math instantly. If you're stuck, draw a quick throwaway line to reset your mental count and start fresh instead of forcing a bad route. Don't ignore the clock, but a slow correct path beats a fast wrong one every time. Look for zero or one tiles — they can absorb extra points without altering your total as much.
