Sharpen your mind with a connect-the-block-style one-line brain training puzzle game. Fill the Rainbow is a fun, simple and beauty relaxing puzzle game with an immersive atmosphere. Your brain becomes more active the more you play. If you think you are an intelligent person, you are in the right place. The more you play the more intelligent you become. A simple but unique and addictive one-line puzzle game that’s completely free to play. During your commute, before you sleep… enjoy downtime with brain training. Fill the Rainbow is just like the classic connect the dots game but without numbers or structure to guide you. Start from the initial dot, then connect all open dots on the board ending in the last dot. Connections are made vertically or horizontally, and without overlap. No specific ordering or correct path is required to solve the puzzle, just that all dots must be connected. Use hints for puzzles that are too hard to solve. Don’t get too cozy—the puzzles get harder as you go along. One-line puzzles are mathematical problems with origins in the early 18th century. First posed in Königsberg, the original puzzle revolved around the town’s Pregel River. Mathematical thinking is said to increase work efficiency and prevent aging. Whether math is your bane or your forte, be sure to give this game a try. You’re sure to get hooked on these puzzles! Simple, Smart, Addictive, Challenging, Relaxing and Fun game. All in one place! Features: - Minimalist design: beautiful colors, awesome audio effects. - Smart level design: more than 900 handcrafted smart levels. - Relaxing atmosphere: rainbow colors and bubbles into the sea. - 3 background colors: blue, purple and red. - 13 Designs of Tiles: Rainbow, Ribbon, Flower & Emoji packs
