DoubleUP is a hybrid incremental/puzzle game inspired by sliding puzzle games like 2048 and Threes. Start with a tiny 2x2 grid with measly 1 tiles and work your way up from there, upgrading the playing field and base tiles, earning achievements for discounts, and unlocking new currencies and powerful upgrades to reach larger and larger tiles. Build up your combo bar my merging tiles each turn in a row. Earn awards by completing challenges to earn a discount on all shop purchases. Data is saved automatically every minute. The text box on the settings menu can be used to backup, restore, or share save data. Enjoy playing this number block game here at Y8.com!
