How to play Slide Mosaic

Slide Mosaic is a sliding picture puzzle with a twist: there is no empty tile. Every level starts by showing you a finished picture for a moment, then scrambles it by sliding rows and columns around. Your job is to slide them back until the picture is whole again.

Drag left or right anywhere along a row and the entire row circular-shifts — the slice that falls off one edge wraps around and reappears on the other side. Drag up or down and the whole column shifts the same way. Because a full line moves at once and nothing ever leaves the grid, the board never breaks apart the way a classic fifteen-puzzle does. A quick flick carries several cells; a slow, deliberate drag nudges just one.

Tap the eye button any time to peek at the target picture, so you always know what you are building toward. Solve the whole board and the frame flashes to celebrate. Your score is the number of cells you slide — fewer is better — and your best solve is saved per difficulty right in your browser.

Why the “no empty tile” rule matters

Traditional sliding puzzles give you one blank square and make you shuffle tiles one at a time around it. Slide Mosaic removes the blank entirely. Every row and every column is a full loop, so you are always moving a complete line of the image. That changes the strategy completely: instead of nudging single tiles, you think in whole rows and columns, lining up bands of the picture and then locking them in with a final column slide.

Difficulty and scoring

Choose your board from the start menu:

Larger boards slice the picture into more pieces and shuffle it with more slides, so an Expert board can take many careful moves to rebuild. Because the scramble is built only from legal slides, every puzzle is always solvable — there is no unsolvable arrangement to get stuck on.

Tips and strategy

• Build one edge first. Solve the top row completely, then work down. Once a band of the picture is correct, only move columns by full loops so you do not disturb it.
• Fix columns last. Rows are easy to eyeball; columns are what lock the final image together. Get the horizontal bands roughly right, then clean up vertically.
• Use the peek often. On abstract pictures it is easy to lose track of where a slice belongs — a quick glance at the target saves wasted slides.
• Slow drags for precision. When you only need to move one cell, drag gently and release without a flick so it snaps exactly one step instead of skidding past.
