Sum Strike — free browser game

Sum Strike puts your reflexes and arithmetic on the same beat. Numbers from 1 to 9 fall from the top across 6 columns; you tap them to add them to the 'bucket' shown in the HUD. On the left of the HUD a fresh TARGET (9-22) appears each round. Your job: land the bucket on the target exactly. When bucket equals target it pops, you score +1, and a new target spawns. Overshoot the target and the bucket clears, your streak ends, and you pay 1 point (the score never goes below 0). Three pops in a row light up a STREAK bonus: each correct pop while the streak holds is worth +2 — overshoot or manually clear the bucket and the streak breaks. The round runs 60 seconds; numbers you miss fall off the bottom without penalty, just lost opportunity. As your score climbs, fall speed and spawn density both ramp up; in late game you have well under a second to commit to each tap. The Space key does double duty: it starts a new run when the round is over, and clears the bucket mid-game when you realise you've added the wrong number — don't wait to overshoot, scrub and replan. R restarts at any time. Strategy tip: don't reflex-grab the biggest number — look across the board and prep a 'combo' for the bucket. For target 14, if two 7s are already lined up, prefer them over chasing a single 9 + 5. When overshoot risk is high, plan to finish with a small number and resist taking the larger tile that's about to slip off.
