Mailbox Catch
Tilt a mailbox flap with a swipe so falling letters slide into the right address bin before the slot overflows.
Letters auto-drop in arcs; swipe the flap left or right to deflect each letter into one of two bins; wrong bin fills a junk meter that ends the round.
Swipe left or right to angle the mailbox flap; tap to flip to the other side of the bin layout.

Sorting template is a top-converting hybrid-casual category: Coin Sort debuted at #8 in AppMagic Q3'25 with $5.4M revenue / 4.8M downloads; rewarded revives + interstitials between rounds map cleanly onto this loop.Coin Sort $5.4M revenue / 4.8M downloads in Q3'25 — proves the two-bin sort monetizes ↗Hybrid-casual puzzle report lists sorting among the top-grossing templates in 2025 ↗
Heavily saturated — Sort It 3D has 10M+ downloads, Coin Sort is a top-10 hybrid-casual title, and sorting is explicitly called out as a leading template; a mailbox re-skin offers almost no differentiation against Supersonic/Lion Studios incumbents.Sort It 3D at 10,000,000+ downloads on Play — incumbent already owns the sort reflex niche ↗Google Play listing confirms mature, long-running competition in this exact mechanic ↗
