NEW: Daily Puzzle - a fresh board every day, same for everyone worldwide. Build streaks, share Wordle-style results. Calm cosmic vibes. 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.
