Mathstack - Sequence Puzzle Love number puzzles? This one's different. Stack your way to victory by building sequences from 1 to 15 (or 15 to 1) across five colorful stacks to clear the board. The catch? There are more cards than space on the board. Think ahead, use your temporary slots wisely, and plan your moves to uncover the cards you need. Three difficulty levels to match your mood: - Easy (1-5) for a quick brain break - Medium (1-10) for a solid challenge - Hard (1-15) for number-crunching pros Simple to learn. Tricky to master. Impossible to put down. Terms of Service: https://hazerim.com/terms-of-service/ Privacy Policy: https://hazerim.com/mathstack/privacy-policy/

Rise. Stack. Breathe. Zen Stack is a calm, minimalist block-stacking game about one simple thing: place with purpose. Tap to drop each block onto the tower. Time it right and the blocks line up perfectly; mistime it and the overhang is shaved away, leaving less room for the next one. The higher you climb, the faster it gets. One screen, one tap, endless focus. No clutter. No pressure. Just a quiet, satisfying climb and the soft snap of a perfect placement. GAME MODES • Classic: the original climb. A steady speed ramp that rewards rhythm and patience. • Zen: slower and more forgiving. Unwind and stack at your own pace. • Precision: fast and unforgiving. For players chasing the top of the leaderboard. Each mode has its own worldwide leaderboard, so you can master the style that suits you. PERFECT DROPS & ZEN FLOW Land a block dead-center for a PERFECT. Chain three perfects in a row to enter Zen flow, and your next three drops score double. Satisfying ripples, gentle haptics and a golden glow reward every clean placement. DAILY CHALLENGES Three fresh goals every day, drawn from 20 challenge types: perfect-drop streaks, towering heights, time in each mode and more. Complete them to earn up to 60 bonus sparks a day. A new mix arrives every midnight. 12 HANDCRAFTED THEMES The whole game restyles to match the look you choose. • Aurora, Sunset, Ocean and Sakura: unlock them by beating your best score. • Monochrome, Neon, Ember Gold and Galaxy: collect sparks or watch an optional video. • Zen Premium: polished Jade Garden and iridescent Moonstone, included with Remove Ads. • The Luxury Collection: Obsidian Royale in black onyx and champagne gold, and Rose Quartz in faceted rose crystal.

ACHIEVEMENTS & LEADERBOARDS Earn 15 achievements, synced with Game Center, and see how you rank against players around the world in every mode. A SECOND CHANCE Topple near the top? Keep your run going with a fresh block and pick up right where you left off. WHY YOU'LL LOVE IT • One-tap controls anyone can play • Elegant visuals, gentle haptics and crisp sound • Quick rounds, perfect for a short break • Play offline and stack anywhere • Clean, minimalist design Prefer no interruptions?
