When all the colorful cool kids at the coffee klatsch create a conga line, you know they're concocting a crazy cotillion. But can you slide the squares in a sequence to spawn a specific shape? That's the challenge behind Mosaic Mingle, a puzzle game by Acoders where your goal is to rebuild an image one square at a time. It's not as easy as it sounds though, because the order of your tiles is restricted by a colorful conga line.
Each tile in the 8x8 mosaic must be slid in from one of the four sides. A tile will keep sliding until it runs into another tile or the edge of the grid. Click one of the outlined spaces in the grid to slide a tile into that spot. Your tiles are offered to you one at a time in the order indicated by the snaking line on the left, with your current tile at the top. The trick here is that the tiles aren't necessarily arranged in a pattern conducive to an easy solve. If you're not careful, you might block out tight corners in the grid, making it impossible to slide blocks into place.
After you've played through the levels in normal mode (where the squares are always in the same order, often in large color clusters), you can tackle them again in challenge mode where the squares are shuffled in a random order. There are 25 easy puzzles and 25 hard puzzles with more colors and trickier patterns to fill. For those who are colorblind, there is an option to add shapes to the tiles and grid, but the black/white icons aren't always the easiest to distinguish. But if you're looking for a puzzle that surprises you with a challenge, jump in the line and rock your mosaic in time!
