The Daily Challenge: a new puzzle every day

Every day there's one purpose-made level that isn't part of any campaign. Everyone in the world gets the same level on the same day, picked by the date, so it works without a server and without an account.

• Unlimited tries. Your best score counts.
• Its own leaderboard. A Game Center board that resets every day at midnight UTC, with friends and global ranks. It's kept separate from your total score.
• Proven solvable. Every daily level is checked by the same solver that tests the campaign levels, so none of them are impossible.
• Free for everyone, even on days when the level is set around a star from a paid campaign.

There are 128 of them to start, spread across all four stars, and a streak counter for the days you win in a row. Sol welcomes you the first time you play.
