About

Dot Link

Features
Read full description

Connect two dots of the same color with blocks, and they disappear. That is the whole rule. No tutorial, no sign-up, no timer. ■ How to play Drag a block from the tray onto any empty space. When two dots of the same color are joined by blocks, the path and both dots clear, and a new pair appears. The round ends when nothing fits anymore. ■ Longer is better Score grows with the square of the path length. Clear the short way now, or take the long way around for far more. ■ Chains Complete two pairs in a single move and a chain fires. The score multiplies and the board lights up. ■ Space is the difficulty Every so often a 3x3 block shows up. You never know when, so you have to keep room for it. That judgement is the game. Works offline. No account needed.
