Explore the Solar System in Planet Formula, a match-3 puzzle game featuring 125 unique levels with engaging objectives. Complete each level by earning points, breaking ice tiles, or collecting coins—all within a set number of moves. Earn special power-ups: - Magic Planets: Match five planets in a row or column to create a magic planet. Swap it to clear all planets of the same type on the board and score big. - Special Planets: Match four planets to create a special planet with a white border. Use it in a match to clear an entire row or column. - Discover combinations like T-chains and L-chains for massive point boosts. Break ice by clearing planets underneath, and remove walls by eliminating adjacent planets. Be strategic — walls grow if no nearby planets are destroyed in the previous move. Accessibility Features: Planet Formula is designed with VoiceOver users in mind: - Tap a grid cell to hear the planet’s type and position. - To move a planet, select it with a single tap, then double-tap to start moving. - Choose the destination with another tap and confirm with a double-tap to complete the move. With simple mechanics and thoughtful design, Planet Formula offers an enjoyable, relaxing experience — perfect for playing at home, during a break, or while commuting. Challenge yourself, earn points, and rise through the ranks in this solar system-inspired puzzle adventure.

About

Gravity Whisper

Features
Read full description

A comet drifts through the cosmos, far from home. Its only hope? You. Gravity Whisper is a physics puzzle game where you create gravity wells with a tap of your finger. Pull, slingshot, and guide a wandering comet through increasingly complex space environments — past black holes, through wormholes, around orbiting planets, and across tidal streams. SIMPLE TO LEARN, HARD TO MASTER Tap and hold anywhere to create a gravity well that pulls the comet toward it. That's it — no buttons, no joysticks. But be careful: touch the comet with your finger and it's gone. Every level is a puzzle of timing, trajectory, and patience. 360 HANDCRAFTED LEVELS Journey through a massive campaign of hand-designed puzzles, each with a unique name and personality. From "First Light" to "Infinite Reflections," every level introduces new spatial challenges that test your intuition and skill. EVER-EVOLVING MECHANICS What starts as a simple physics puzzle evolves into something far deeper. New mechanics are introduced gradually: • Black Holes — gravitational traps that devour the comet • Wormholes — teleport across the level in an instant • Gravity Ropes — tethered obstacles that block your path • Moving Planets — orbiting bodies that patrol the void • White Holes — repulsive forces that push the comet away • Gravity Lenses — bend the comet's trajectory mid-flight • Pulsars — blinking hazards with deadly timing windows • Asteroid Belts — rings of spinning rocks • Magnetic Gates & Switches — toggle barriers on and off • Nebula Fog — hidden dangers shrouded in mist • Tidal Streams — directional currents that sweep the comet • Mirrors — bounce the comet off reflective surfaces EARN STARS, UNLOCK GATES Complete each level before time runs out to earn up to 3 stars. Finish faster for a higher rating. Every 10 levels, a Star Gate challenges you to prove your mastery — earn 90% of all available stars to proceed. BEAUTIFUL & ATMOSPHERIC A soothing cosmic aesthetic with smooth gradients, glowing particles, and poetic level names that tell the story of a comet finding its way home. FEATURES • 360 unique puzzle levels • 12 distinct game mechanics introduced progressively • 3-star rating system with time-based scoring • Star Gate checkpoints every 10 levels • Offline-ready — no internet required to play • Haptic feedback for an immersive experience • Localized in 40 languages • No ads. Ever.

Verdict

The call

The clearest difference is ads: Gravity Whisper at none against Planet Formula's shown. Gravity Whisper also leads on update cadence (every 2 weeks vs every 2 months). Planet Formula's advantage is device support (4 vs 2) and iOS requirement (13.0 vs 17.6). On price and in-app purchases there is nothing between them.
