Fill the Jar
Snowline is a merge-drop physics puzzle. Aim from the rail and drop snowballs into the jar — when two of the same size touch, they fuse into the next size up, from tiny Snowflake all the way to the glowing Aurora Core. The pile jostles, rolls, and stacks under real physics, and the run ends only when it holds above the frost line. Endless, free, and a little bit hypnotic.

Move the mouse to aim, click or press space to drop. On mobile, drag on the jar to aim and lift your finger to release. One gesture is the whole interface — the depth is all in where you drop.

How a run works
Every drop scores through merges: each fusion is worth the value of the snowball it creates, doubling per tier up to 512 points for an Aurora Core. Merges chain — a fresh ball that lands touching its twin fuses again instantly, cascading several tiers in one drop and collapsing the pile's height when you need it most. Merging two Aurora Cores is the jackpot: a 1,000-point bonus, with the pair collapsing back into a single Snowflake.
The dashed frost line near the top of the jar is the only way to lose. A momentary bounce over it is forgiven, but a pile that holds above the line for a second ends the run. High scores land on a local leaderboard saved in your browser — no account, just three initials and a number to beat next time.
