Tower Stay
Build a vertical hotel: tap to drop guests into floors, swipe to merge same-floor guests into a suite that earns coins per second.
Tap an open floor to drop a guest; two guests on the same floor merge into one 'suite' tenant earning more passively.
One-thumb: tap a floor to drop a guest in, swipe a guest down a floor to merge.
Vertical idle-merge with hotel-skin + idle coin generation — Hotel Legacy's renovation tone compressed to a single screen.
Hotel Legacy's 4.3-star reviews and merge-mania App Store chart rank prove merge-tower mechanics still print.
Hotel Legacy entered at #15 with ~$60K/day in 30 days, but Gamigion notes it is literally 'Tasty Travels with a hotel theme' — a proven wheel, not a new hook.Hotel Legacy teardown showing $60K/day at launch, #15 chart entry, copy-of-Tasty-Travels framing. ↗
Merge is a high-retention, low-virality category: players run ~6 titles simultaneously (per Gamigion) and growth comes from UA creatives, not organic social sharing.Players hop across 6 merge titles when energy runs out; category is UA/creative-driven, not streamer/TikTok-driven. ↗
One-thumb tap/swipe merge is buildable — multiple Merge Tower templates exist on Unity Asset Store and Fab — but a tuned merge economy + idle coin curve still needs real balancing work.Off-the-shelf Merge Tower Defense hypercasual template lowers build cost but not economy design cost. ↗
Merge is one of the top-grossing casual genres: Gossip Harbor ~$95M/mo, Hotel Legacy already at ~$60K/day one month in, strong rewarded-ad + IAP patterns confirmed.Gossip Harbor #4 globally, Hotel Legacy $60K/day tier-one, 4.4–4.5★ with 750k+ downloads. ↗Hotel Legacy 4.4/5 with 750k+ downloads, validates hotel-merge revenue profile. ↗
Catastrophically crowded: Gossip Harbor, Tasty Travels, Travel Town, Flambe, Hotel Legacy, Merge Hotel: Design Dreams, Merge Hotel Story, My Perfect Hotel — and Gamigion explicitly says 'category rewards execution over originality' with no real innovation likely for 2 years.'Don't expect real merge innovation soon… copy the proven core, out-execute on creatives, win.' ↗
