Countdown Sequence is a snappy number puzzle about clearing grids by drawing countdown chains.

Drag through tiles to create a countdown sequence, jump through clear tiles, achieve combinations and use special tiles to complete grid and boost your score! The longer the sequence, the more points you will get! How far can you go?

Made for GMTK Game Jam 2026 with the theme Countdown.

P.S.
Countdown sequence is a chain of descending numbers with difference of 1 between neighbors. The chain can start from any number and stop at any lower number, but it cannot skip numbers unless a special tile allows it.
Examples:
8 -> 7 -> 6 -> 5 -> 4
10 -> 9 -> 8 -> 7
3 -> 2 -> 1

Base score is calculated based on sequence length with arithmetic progression with base 100. So sequence of length 3 will get 100 + 200 + 300 = 600 base points and sequence of length 10 will get 100 + 200 + ... + 1000 = 4500.

P.S.S.
Everything is controlled by mouse.
If you want to revisit tutorial, it can be done from setting panel (top left icon button).

You can select sequence tiles over empty cells!
