Pebble Skip

Flick a pebble across water and try to beat your skip count before the next wave crashes.

Core mechanic

Tap one side of the screen to choose launch angle, hold-release to set power; the pebble skips across water based on physics until it sinks or a wave crashes; each successful skip stacks a multiplier before the wave resets the round.

Controls

Tap left or right of center to set angle, then hold and release to set power; one launch per wave.

Theme

Calm lake at golden hour with low rolling waves.

Why now

Skipping stones is a universal nostalgia micro-moment; wave-cycle urgency layers hypercasual timing onto it.

Hook
5/10

Skipping stones is a nostalgic micro-moment with proven gesture appeal, but already adapted by multiple existing apps in a near-identical tap-timing format — hook is real but not differentiated.'Stone Skip' by Kebohou: tap to time physics-driven bounces, collect coins, chase high scores — near-identical core'Stone Skipping' on APKPure: 'tap perfectly to keep your stone bouncing, avoid obstacles' — direct mechanic overlap

Virality
3/10

Searches for viral/TikTok pebble-skip content returned no meaningful results; the existing Apple Watch title and Android 'Stone Skip' show modest scale, suggesting the visual is calm rather than clip-worthy.Apple Watch 'Skipping Stone' release shows the concept ships but isn't generating visible viral momentum

Simplicity
8/10

One launch per wave, two controls (tap-side + hold-release), single physics outcome — trivially prototypable as a single-screen hypercasual.Existing 'Stone Skip' demonstrates the mechanic reduces to a single-input arcade with collectible loops

Monetization
5/10

Tap-timing hypercasual format supports interstitial between waves and a coin/doubler rewarded-ad loop, but session length is short and spend ceiling is mid — comparable to other minimalist physics arcades.'Stone Skip' uses coin collection + best-run saves, the standard rewarded-ad / unlock pattern for the genre

Whitespace
3/10

At least three direct competitors already ship the core mechanic (Android 'Stone Skip', 'Stone Skipping' APK, Apple Watch 'Skipping Stone'); the wave-cycle reset is a thin differentiator in a narrow niche.Competing Android title ships the same tap-to-skip loopSecond competing APK with obstacle-dodging variantThird competing title on Apple Watch with wrist-flick controls
