A free falling gem puzzle, and a block puzzle too
In Cave-in, clusters of three to five gems drop down a 9-wide mine shaft. Fill a row to clear it, or touch four gems of the same kind and they shatter. The loose gems fall, and if they line up again, that's a chain worth more. Clearing fills Luna's pickaxe; when it's full, Dig out the bottom two rows. Spark gems blast everything around them. Today's dig gives everyone the same clusters, so you can compare scores and send a challenge link.
Dig Site is the calm one: place three shapes at a time on an 8×8 board, clear full rows and columns, and keep going as long as there's room.
