Tower Tap
One-thumb vertical tower climb where each floor introduces one rule (jump-only, duck-only, hold-to-glide) and you tap as fast as possible without touching the wrong tile type.
Climb a tower one tap at a time, switching between jump/duck/hold inputs to match the floor's rule, racing a ghost opponent.
One thumb: tap, hold, swipe up — input changes per floor.
Rainbow-tiered tower floors echoing Rainbow Obby's many distinct modes (Ladder, Plane, Knockout, etc.) stripped into micro-rules.
Rainbow Obby's selling point is mode variety (10+ game modes); we compress that variety into per-floor rule twists instead of separate modes.
Per-floor rule-switch is a genuine curiosity hook, but the 'Tower Tap' name is already taken (itch.io one-button stacker) and Rainbow Obby already sells mode-variety novelty on Poki, diluting the differentiation.Rainbow Obby already markets 10+ game modes as its hook ↗Existing 'Tower Tap' game by happydale — name collision risk ↗
Tap-timing stackers (Tower Stack, Tap Tap Dash) and obby racers are proven shareable, but 'fail at floor N' is now a commoditized mobile moment; the ghost-opponent race adds some moment-of-tension shareability but not a standout viral mechanic.Tap Tap Dash shows tap-tap stacker as a proven viral format ↗Obby Rainbow Tower is a direct thematic competitor ↗
One-thumb tap/hold/swipe is a clean input surface, but the per-floor rule change forces tutorialization/practice per new rule, raising cognitive load above pure one-tap games.Tap & timing noted as dominant but per-mode rule changes are NOT listed as top mechanics — suggesting added friction ↗
Hypercasual tap games monetize via interstitials + rewarded revives, and the ghost-opponent race creates a clean rewarded-video slot; however, Sensor Tower data shows mobile downloads shrinking and revenue flat ($82B 2025), meaning more crowded ad inventory per user.Confirms standard ad-monetized scaling pattern for one-thumb hypercasual ↗Sensor Tower: downloads continuing to shrink, revenue holding flat — harder CPI ↗
Crowded: Rainbow Obby (Poki trending), Obby Rainbow Tower, the pre-existing Tower Tap on itch.io, Tap Tap Dash, and the broader tap-timing hypercasual category all occupy adjacent space; 'per-floor rule twist' is a thin wedge against mode-based obbies.Obby Rainbow Tower — direct tower-climb one-thumb competitor on Poki ↗Poki's full obby category shows heavy saturation of climb/obstacle games ↗Name already taken by existing tap-stacker ↗
