Previously all sand colors were just unlocked from the start. Now:
You begin with 4 base colors per palette (free).
3 additional color slots can be purchased with coins (up to 7 colors total per palette).
More active colors = harder to read the board, but you get a score bonus for it: each color above the base 4 adds +8% score. Running the full 7 colors gives you a solid +24% bonus.
You can toggle which unlocked colors are active at any time - as long as at least 4 stay active.
🪛 Fixed
Daily Challenge - leaderboard fix
Fixed a bug where the Daily Challenge score wasn't resetting properly. If you set a good score and then didn't play for a while (even a full week), you could stay locked in at #1 on the leaderboard the entire time, since your old score never expired or got replaced. Daily Challenge standings now refresh correctly, so the board reflects actual recent play instead of a stale score from days ago.
