About Arithmetic Line
Welcome to Arithmetic Line, an engaging game that combines the thrill of calculation with the challenge of ingenuity. In this unique experience, players will find problems displayed above their character's head. The objective is to solve these mathematical puzzles by accurately determining the operations needed to arrive at the correct answer. With each problem, players must think quickly and strategically
The genre lives on enemies with distinct behaviours, ammunition or cooldown management and satisfying hit feedback. Arithmetic Line understands that, and it shows in the first minute of play. The skills it leans on are target prioritisation and resource management; both improve noticeably after a few sessions.
How to play Arithmetic Line
- Start by clicking the big play button. Arithmetic Line loads inside the frame; give it a moment, especially on a slow connection.
- Follow the on-screen prompts. The developer describes the controls like this: Click mouse
- Take a few practice shots at the first targets to learn the aim speed, then move on to prioritising the dangerous enemies.
- When you are comfortable, set a target: a score to beat, a level to clear or a time to shave. Small goals are what make Arithmetic Line stick.

Tips and tricks
- Prioritise the threat that will hurt you soonest, not the one that is closest or biggest. Fast enemies before slow ones, shooters before melee.
- If there is a reload, reload during quiet moments — never in the middle of a wave.
- Learn the spawn points. Most levels reuse the same few entry points, and knowing them turns panic into routine.
- Aim first, then shoot. Spraying costs time or ammo and rarely helps; a single well-placed shot almost always beats three rushed ones.
Who will enjoy it
We would recommend Arithmetic Line to players who like precision, quick targeting and progressively tougher waves. A typical session is levels of a few minutes each, with longer runs in survival modes. How hard is it? Approachable at first, with a steep climb in the later waves. It works on phones and tablets with touch controls, and on desktop with a mouse or keyboard.
