15 Number Slide: Logic Puzzle is a fresh take on the timeless sliding numbers puzzle — also known as Puzzle 15 — where the goal is to arrange tiles in sequence from the top-left to the bottom-right corner, leaving the last space empty. The minimalist design and intuitive tap mechanic make each round clear, calming, and deeply satisfying.
Designed for fine motor comfort. Instead of sliding tiles, you simply tap to move them — perfect for everyone, including those with reduced hand flexibility or stiffness. The mechanic keeps gameplay effortless yet mentally engaging. Fans of sliding puzzle games will recognize the familiar logic, but here it’s reinvented with a soft, modern rhythm that encourages focus without pressure.
This reinvented classic is more than entertainment. It can serve as a gentle ritual to maintain cognitive vitality, support memory, and bring clarity to a busy day. Loved by thinkers and enjoyed by casual players alike, this relaxing brain game fits both quick breaks and deep focus sessions. Behind its simplicity lies the quiet rhythm of math — balance, order, and the beauty of pure logic.
The game offers 10 carefully designed difficulty levels — from light boards for beginners to advanced layouts for puzzle enthusiasts. Each level adds new strategic depth, rewarding patience, precision, and presence of mind.
Truly simple. No clutter, no manuals, no distractions. Just open the app, choose a level, and begin your daily slides. The clean, calming design helps your attention stay on logic and movement — not on noise or ads.
Morning routine for productivity. Only 60 seconds. Use Countdown mode in the morning to refresh focus before the day begins, or Stopwatch mode to play at your own pace. Sometimes the most productive thing you can do is relax. Feel a gentle brain rush — a one-minute puzzle that clears your mind and re-energizes your day.
Track your progress. A built-in Step Counter records every move, turning each puzzle into a measurable challenge. You can refine your approach, compete with yourself, and enjoy steady improvement. Every solved puzzle becomes a small but meaningful victory — proof that you trained your brain today.
Game Modes

But the checkmark that you’ve trained your brain today will already be there. Just 60 seconds is enough for a quick brain boost without getting stuck — perfect for morning wake-ups or mental refresh.
