About

Double Infinity

Features
Read full description

Double Infinity is a relaxing number-merging puzzle where you link matching tiles and chase the ultimate high score: Infinity. On a serene 5×8 grid, swipe in any direction (including diagonals) to build chains of numbers. Connect matching values or smart doubles (think 2 → 2 → 4) to merge them into higher powers of two. Longer chains create bigger leaps and drop a special Star wildcard — a powerful tile that matches anything and helps open new paths. After each merge, gravity pulls everything down and fresh tiles cascade in, keeping the calm flow going. No timers. No lives. No pressure. Just satisfying merges, beautiful major-scale chimes that rise with your chain, and a peaceful “one more merge” feeling. Watch your board max climb from 1 all the way to Infinity in a deeply rewarding, offline-first experience. Key Features Intuitive drag-to-chain gameplay with 8-direction linking Star wildcards earned from long chains (only one on the board at a time) Four rechargeable power-ups: Mega Merge, Area Bomb, Board Shuffle, and Undo Stunning deep-blue aesthetic with colorful power-of-2 tiles, smooth animations, and haptics Milestone celebrations and a spectacular Infinity finale when you reach the top Automatic daily power-up reset at midnight + Premium benefits Fully playable offline Perfect for short relaxing sessions or long puzzle flows. Progress is saved automatically so you can pick up exactly where you left off. Double Infinity is free to play with optional ads. One-time Premium unlock removes ads and doubles power-up recharge speed from merges. Whether you’re a fan of number merge games, link puzzles, or just want a calm, beautiful brain-teaser, Double Infinity delivers endless satisfying play. Link numbers. Merge higher. Reach Infinity.
