SURVIVE THE GRID Tick00 is an electrifying, fast-paced puzzle game that will push your mental math skills and reflexes to their absolute limits. Set against a stunning, retro-futuristic synthwave aesthetic, your goal is simple: clear the grid by building mathematical equations before the clock runs out. HOW TO PLAY: • Connect adjacent numbers on the grid to form an equation (e.g., 2 + 3 = 5). • Swipe to select your numbers and watch them vanish, granting you precious extra seconds. • The faster you solve, the longer you survive! FEATURES: • Endless Survival Mode: The grid keeps regenerating and the numbers get harder. How long can you last before the timer hits 0.00? • Chain Combos: String together rapid solutions to build your chain multiplier and earn massive time bonuses. • Sleek Aesthetic: Immerse yourself in a beautifully crafted dark-mode UI with neon accents, dynamic floating text, and fluid haptic feedback. • Brain Training: Sharpen your arithmetic skills under pressure. It's easy to learn, but incredibly difficult to master. • Completely Offline: No internet? No problem. Tick00 is a fully offline experience with zero interruptions. No ads, no tracking, just pure gameplay. Are your reflexes sharp enough to beat the clock? Download Tick00 and find out!
