## What is Slide15?

Slide15 is a classic 15-puzzle for iPhone. Slide numbered tiles and arrange the numbers in order - on square grids of varying sizes and on a growing library of unique shape-based layouts. Cosmic zen atmosphere, no timers, no mid-game ads.

LOOKING FOR A CALM BRAIN GAME?
If you love sliding puzzles, klotski, or the original 15-puzzle, Slide15 gives you the full classic - plus Shapes mode with unique non-rectangular grids you won't find anywhere else, and a Weekly Cosmic Challenge: solve a series of mini-puzzles to reveal a real astronomy photograph piece by piece.

GAME MODES
• Classic - square grids in a range of sizes, from compact to larger boards. The pure sliding-number puzzle, a mechanic refined since the 1870s.
• Shapes - non-rectangular layouts on bigger boards: L-corner, T-cross, plus, U-turn, frame, H-block, and more. New shapes added in every update.
• Weekly Challenge - solve a series of mini-puzzles to progressively unlock a new cosmic photograph every Monday. Real astronomy photos, not AI-generated filler. (Internet required only to download the weekly image.)

WHY PLAYERS PICK SLIDE15
• Zero timers. Zero lives. Zero ads mid-move. Pause whenever, come back whenever - your progress stays.
• Every level is handcrafted - no procedural filler.
• Classic and Shapes modes play fully offline - on planes, subways, anywhere without Wi-Fi.
• Cosmic visuals: nebulae, parallax starfields, and a smooth 3D planet-based level map instead of a standard menu.
• Smart assists: haptic feedback, undo up to five moves, solution preview, and auto-hint after a pause.

PERFECT FOR
• Unwinding after work when timers in other games have become exhausting.
• Short breaks: waiting rooms, commutes, lunch, quiet evenings.
• Players who find classic 15-puzzles too plain and mobile clones too cluttered with ads and gimmicks.
• Fans of minimalist aesthetics and astronomy photography.
• Logic, spatial reasoning, and brain training - without fake rewards or push notifications.

WHAT SLIDE15 IS NOT
Not a match-3, not a block puzzle, not a jigsaw, not an energy-gated free-to-play. If you want one of those, there are thousands. If you want a quiet, modern take on the classic sliding number puzzle - Slide15 is built for you.

Download Slide15 and start with 3×3. A one-time purchase unlocks every level with no ads - no subscriptions.

## Version history (last 5 releases)

### 1.2.1 — 2026-05-06

A polish update – small things, big difference.

• New vector icons across the level-select screen. Play, Open now, and Watch Ad buttons all swapped to crisp SF Symbol glyphs.
• Clearer swipe affordance between planets – refreshed chevrons with a gentle bobbing animation.
• Two-style Premium banner – gold during welcome offers, cosmic-calm afterwards, so the visuals follow the actual offer.
• Fixed: the how-to-play hint arrow stayed on the board after closing the help dialog.
• Fewer accidental taps on the play screen – tightened the bottom-of-grid layout.
• Localized confirmations after unlocking a level via Watch Ad (no more English-only alert on the Russian and Spanish builds).
• Cleaner victory subtitle copy in all three languages.

Thanks for playing – see you in the next puzzle.
