This isn’t a normal calculator – it’s a fast-paced number strategy game. You get a target number, a ticking timer, limited operator uses… and you have to figure out the perfect sequence to hit the target before time runs out. Plan your steps, manage your + / − / × / ÷ ammo, unlock missing digits and push your run as far as you can through 250 handcrafted game levels. HOW IT WORKS Start a run from Level 1. Each level gives you a target number and a limited set of operations. Type your calculation like a real calculator – but every operator use matters. Hit the exact target before the level timer hits zero to move on. Fail the level and your run is over… unless you have a Pass Ticket. FEATURES 250 LEVELS, RISING DIFFICULTY Climb from easy warm-up levels to brutal “God” tiers where time is tight and digits are missing. LIMITED OPERATORS, INFINITE STRATEGY / − / × / ÷ are all ammo-based. Run out, and you’ll have to rely on smart planning or items to survive. ITEMS & DIGIT UNLOCKS Use items to unlock disabled digits (0–9), slow down time, add extra seconds, boost base level time or make an operator unlimited for a single level. INVENTORY & SHOP Earn coins by playing well and spend them on ammo, time boosts and Pass Tickets. Every purchase changes how your next levels play out. FAIR LEADERBOARDS Compete in local leaderboards around the world, while the global leaderboard only counts your best record from your home country. SPEEDRUN-STYLE RUNS Your total run time from Level 1 is tracked. Higher levels + faster clears = better ranking.

Margin is a pursuit puzzle you win with your head, not your thumbs. Every level is a small board. You move one square at a time. So do the hunters — and they always take the step that brings them closest to you. That is the whole rule, and it is also the whole trick: because you know exactly what they will do, you can decide where they end up. An arrow above each hunter shows the step it is about to take. Read the arrows, and a level stops being a chase and becomes a plan: pull the pack one way, slip through the gap they leave, walk out through the exit. • Three tiers: Easy, Medium and Hard. Each one puts more hunters on the board and less room between them. • Daily Board: one board for everyone, every day, separately for Medium and Hard. Solve it to earn 200 points on Medium or 400 on Hard, and claim your spot in the daily ranking. • Challenge a friend: send a board you've won as a link. They play the exact same one, then can watch your game step by step. • 48 titles to earn, plus weekly and all-time leaderboards on Game Center. • Every level is generated and then solved by the game before you ever see it. If it is offered to you, it can be beaten. • Every board shows its minimum move count. Each extra move costs a point (up to 5), so the shortest escape earns the most. • A hint when you are stuck, and a fresh board whenever you want one. • No timers, no lives, no energy to wait for. Think as long as you like. • Plays in portrait, one thumb, anywhere. There is no margin for error. There is exactly one square of it.

Verdict
The clearest difference is ads: GlitchCALC at none against GOA's shown. GOA's advantage is update cadence (daily vs every 5 days). On price, in-app purchases, device support and iOS requirement there is nothing between them.
