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.

Verdict
The clearest difference is update cadence: Dot Link at weekly against Sudoku's every 4 months. Sudoku's advantage is iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.
