Social media dilutes focus; "Entropy: Zero" sharpens it.  Stop the doom scroll. Switch to a puzzle that pulls your brain from fog into flow state. Choose how you train your attention across two distinct modes, designed to replace mindless scrolling with tactical satisfaction: Levels Mode:  Master Your Progress! Rebuild your focus step-by-step across 80 intense levels.  Start on a manageable 8x8 grid and fight your way to the chaotic, high-speed 14x14 final stages.  Every level you beat is a tangible measure of your growing mental sharpness. Survival Mode:  Test Your Endurance! How long can you hold your attention under fire? In this endless mode, the entropy never stops. Push your concentration to its absolute limit as you manage escalating pressure and lock into a deep, sustained flow state. SYSTEM FEATURES & MECHANICS: • Precision is Everything: Plan your moves carefully. Every move demands total focus. Aim for efficiency, not just speed. • Risk vs. Reward: You can’t just tap wildly. Placing a patch on healthy territory causes Collateral Damage, accelerating the infection. • Tactical Arsenal: The current shape doesn't fit? "Skip" it to find the perfect piece to heal the grid. • Critical Stakes: The system reaches critical failure at exactly 80% corruption. Fix the tiles before the screen is overrun. • Par Times & Integrity: Earn high-score bonuses for maintaining your "Survival Integrity" and beating level Par Times. • Cyberpunk Aesthetic: Immerse yourself in a sleek, glowing neon cyber-interface. Order has collapsed. Chaos is spreading. Enter the grid and restore balance in Entropy, a tactical puzzle game where every move counts. The system reaches critical failure at 80% corruption. Can you hold back the chaos?

Read full description

Star Battle is a logic puzzle. Place stars on the grid so every row, column, and colored region holds exactly the right number of them. The catch: no two stars can ever touch, not even diagonally. Features: • One-tap stars: tap a cell for a star, drag across cells to dot a whole run as empty • Hold a cell for a single dot, no mode switching • Undo any move with a single tap • Region indicators show which areas still need stars • Optional row and column completion markers • Optional adjacency highlighting reveals cells blocked by nearby stars • A star counter tracks your progress toward the target • Three sizes to grow into: 6x6 Easy, 8x8 Medium, 10x10 Hard • Progress saves automatically, so you can stop and pick up later • Stats and best times for every difficulty • Plays fully offline Spatial, satisfying, and all about smart elimination. Fans of Sudoku, Minesweeper, and logic puzzles tend to get hooked fast.
