Slide Mono & Watch

Mono Slide is a sliding picture puzzle for a tiny grayscale handheld.

Every stage scrambles a different picture into tiles with one empty space. Slide them back into place to rebuild the image — and only when it's whole is its name revealed. The picture is your map; the gap is your only room to move.

100 stages, easy to hard:

- A gentle warm-up on 3x3 grids

- Climbing through 3x4, 4x3 and 4x4

- Up to a 4x5 and 5x5 gauntlet of dense, detailed pictures

Three difficulties:

- EASY — numbered tiles, an out-of-place highlight, and a progress gauge

- NORMAL — keeps the numbers, drops the gauge

- HARD — no numbers, scrambled far harder; the picture alone guides you

Features:

- 100 hand-curated grayscale pictures — animals, nature, places and objects

- Slide with a d-pad or tap-and-slide whole rows by touch

- Stage names stay hidden until you solve them

- Linear unlock — clear one to open the next

- WATCH mode: an AI solves a random stage in time with a live on-screen clock, so a parked device doubles as a desk clock

No timers, no pressure — just you, a scrambled picture, and one empty square.
