Open twenty handcrafted number cases in Number Match Ledger. Tap two orthogonally adjacent digits when they are equal or add up to ten. Cleared evidence leaves real gaps in the file, so spend your limited COMPACT actions carefully to pack survivors and reveal the next authored strip. Earn up to three stars for clean work, use coin hints when a case turns cold, and replay closed files to improve your record. Normal play is free; the clearly labeled optional rewarded AD on Home grants coins only after a completed reward.
