Wooden 15 Puzzle: Number Slide GAME
Seven board sizes: 3x3, 4x4, 5x5, 6x6, 7x7, 8x8 and a genuinely hard 9x9.
All unlocked from install. No grind, no lives, no timers pushing you.
Works fully offline — plane, metro, anywhere with no signal.
A clean, classic sliding number puzzle — the one you already know how to play.
Slide the numbered wooden tiles until they run 1, 2, 3… in order, with the empty
space in the corner. That's the whole game. No tutorial, no timers pushing you,
no lives to wait for.
SEVEN BOARD SIZES
Start at 3×3 and work up to a genuinely difficult 9×9. Every size is unlocked
from the moment you install — nothing to grind for.
TAP OR SWIPE
Tap any tile in the empty space's row or column and the whole line slides at
once. Or swipe a tile directly. Both work; use whichever feels natural.
BEAT YOUR OWN TIME
Your best time is tracked separately for each board size, alongside a lifetime
move counter. Leave mid-puzzle and it's waiting exactly where you left it.
WHEN YOU'RE STUCK
Undo any move, or ask for a hint that points at a tile actually worth moving.
Shuffle for a fresh board whenever you like.
PLAYS ANYWHERE
The game itself works entirely offline — on a plane, on the metro, anywhere with
no signal.
Carved oak boards, engraved numerals, and a quiet wooden knock as each tile lands.
Free to play.
