Split-Brain Slide

One gesture, two minds: each swipe pulls the two halves of the grid the opposite way, so you must rebuild a single picture across a stubborn seam.

How to play

This is a looping sliding-tile puzzle with no blank space. A vertical swipe scrolls the left-half columns one way and the right-half columns the other; a horizontal swipe splits the top and bottom rows oppositely. Untangle the scramble until the tiles form one ordered picture spanning the seam.

• Every move is a cyclic shift, so the puzzle is always solvable and any move can be undone.
• Whole-board swipes move both halves at once — the heart of the challenge.
• You can also nudge a single row or column for fine adjustments.
• Solve in as few moves and as little time as possible for a higher score.

Controls

• Desktop: Up/Down arrows (or W/S) swipe columns, Left/Right (or A/D) swipe rows. Click a tile to nudge its column, shift-click to nudge its row. Buttons for New, Undo and Reset.
• Phone & tablet: drag across the grid to swipe in that direction, and tap a tile to nudge a single line.

Game modes

• Daily: one shared seeded scramble per day across 4×4, 4×6 and 6×6 sizes.
• Practice: fresh scrambles on demand at any size.

Tips & strategy

• Solve one half-column or half-row at a time, then use single-line nudges to lock tiles without disturbing the rest.
• Remember every swipe affects both halves oppositely — plan moves that fix one side without wrecking the other.
• Lean on Undo to experiment; since moves are reversible, you can test a sequence and step it back.
