Pro Puzzle

Swipe horizontal and vertical lines until they snap into a perfect plus. Can you clear the board without getting stuck?

There's a quiet satisfaction in dragging a line across the grid and watching it lock into place. Pro Puzzle is built on that tiny dopamine hit — every successful merge feels like cracking a mini logic problem. You're not just connecting dots; you're eyeballing intersections, predicting how one move opens up two more, and occasionally cursing under your breath when you trap yourself. I got stuck for a solid minute on level 7 before realizing the vertical line could intersect the horizontal one from the other side. The plus just popped, and my brain did a little flip. That's the loop: the game keeps presenting these simple-looking boards, but the solution is never quite where you first look. The swipe controls are smooth on mobile, though a mouse works fine on desktop. It's one of those rare puzzle games that doesn't need flashy graphics or noise — just clean lines, a calm backdrop, and a slowly tightening knot in your temples. If you're the type who plays Sudoku on the toilet or mentally rearranges IKEA furniture diagrams, this will scratch that itch. Some levels feel impossible for a minute, then the pattern reveals itself and you feel like a genius. Then you hit the next level and the cycle starts again.

Swipe and combine vertical and horisontal lines, to get a plus

Look for intersections before making a move — a plus only forms where both lines cross. Try placing the longer line first, then slot the shorter one across it. Don't fill the grid edge to edge; leave a gap for the second line to slide in. If a line won't go where you want, shift it one cell over — sometimes that frees the perpendicular path. When stuck, undo or restart the level instead of forcing random swipes. Watch for subtle grid outlines that hint where a plus might belong.
