7 PLANETS is a relaxing yet challenging logic puzzle game with wooden balls, brain-teasing mechanics, and the timeless feel of a classic board game. Roll and match colourful marbles on a beautifully crafted wooden board, solve puzzles at your own pace, and train your brain with simple but deeply rewarding gameplay. A Puzzle with History 7 PLANETS has been on the App Store for over 15 years and is inspired by a beloved tabletop puzzle first introduced in 1985. It preserves the charm of the original game while bringing its clever logic challenges to modern mobile devices. You start with a wooden board containing 28 balls in 7 different colours. Your objective is simple: restore order by placing every ball into its correct row. The challenge is that when you move one ball, the entire row moves with it. Since the balls are shuffled differently every game, every puzzle presents a unique challenge. 5 Game Modes • One Planet – Match balls using only one randomly selected target colour. Fast, accessible, and perfect for short play sessions. • 7 Planets – The classic experience. Match all seven colours to their fixed positions on the board and improve your strategy over time. • Daily Planets – A new challenge every day. All players around the world receive exactly the same board and compete to achieve the best time and move count before a new puzzle arrives the next day. • Online Duel – Challenge friends or compete against players online in live head-to-head matches to prove who can solve the puzzle faster. • Black Planets – The ultimate challenge. Target colours are shuffled and a mysterious black planet blocks your path, creating entirely new strategic possibilities. This special mode appears only occasionally, making every appearance a unique event. Compete & Improve • Unlock 15 achievements • Climb 5 leaderboards • Improve your time and move count • Compare your skills with players around the world • Master increasingly difficult challenges Whether you are looking for a relaxing puzzle, a daily brain workout, or competitive challenges, 7 PLANETS offers a unique wooden puzzle experience that is easy to learn and rewarding to master.
