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.
