Merge Fill

Drag your finger across the dots to carve out territory, then race to fill the board before your opponent locks you out.

Merge Fill puts two players head-to-head on a shared board full of dots. You tap and drag to connect nearby dots, drawing a line that seals off whatever territory you've claimed. The goal sounds simple—fill more of the board than the other player—but every move opens a chance to steal space or get cut off. I kept coming back because the tension ramps up fast: one miscalculated drag and your opponent snakes a line straight through the area you were building toward. The real hook is how dirty the competition feels. You'll spend a few seconds planning a big sweep across the top edge, only to watch your rival connect two dots that slice your unfinished region in half. That moment—when you realize you should have cut them off two turns ago—stings every time. The controls respond instantly, and while the concept is easy to pick up, the board fills up quicker than you'd expect, forcing you to think about both offense and defense at once. Because it's a browser game, you don't need to worry about installs or logins. Just open it up and either play against a friend on the same device (pass-and-play works fine) or challenge the built-in AI if nobody's around. It's the kind of game that starts as a quick distraction and turns into a half-hour grudge match. Don't underestimate the corners—they're easy to grab early and nearly impossible to take back.

Tap or tap and drag to connect the dots. Fill the entire board to complete each level.

Always secure the corners early; once surrounded, they can't be stolen back. Watch your opponent's drag path—if they're heading for a cluster, cut them off before they reach it. Chain your lines through multiple dots in one smooth motion to lock off large areas at once. Use fast flicks for straight sections but slow down on curves so you don't miss a dot and break your line. If you're losing, focus on blocking their biggest open region instead of expanding your own. Play a few rounds against the AI before challenging a friend to learn the timing of drags.
