Drop-merge number game
Drop. Merge. Climb.
Drop numbered tiles into columns. Matching neighbors merge upward into stronger tiles. Keep the stack alive, chase the peak, and don't overflow.
Free daily run · Pro leaderboards · One StackForge account
How it plays
A tiny rule set with a big ceiling.
Drop
Choose a column. The next tile falls to the lowest open spot.
Merge
Touching tiles with the same value collapse into the next number.
Climb
Cascades can chain into higher peaks. The run ends when a column overflows.
Daily climb
One seeded run each day. Everyone plays the same tile stream and compares the climb.
Friend challenges
Share your code, add friends, and answer head-to-head score challenges.
Ranked leaderboard
Pro players can see the daily board, their placement, and the top climbers.
