NimbusArc

NimbusArc is a focused offline math practice game that turns arithmetic, algebra and geometry into a hands-on puzzle.

Floating symbol nodes drift across a calm cloud canvas. Each node carries a number, a variable, an operator or an equals sign. Your task is to tap the nodes in order, build a valid equation, and submit it before you run out of moves. Every puzzle is assembled from real equations, so a solution always exists within the move limit.

Three chapters guide steady progress:
- Arithmetic Basics practices addition and subtraction with small, friendly numbers.
- Algebra Variables introduces multiplication, division and named variables with a fixed value shown above the board.
- Geometry and Powers brings in angle sums, exponents and square roots for tighter reasoning.

Each chapter opens with five guided levels that explain the rules, then continues with endless generated practice so the combinations never repeat.

Short, focused rounds
A round takes about a minute. Submit a correct equation and the linked nodes lock in with a soft glow. Submit an invalid one and a clear message explains why, such as a zero divisor or an undefined variable. Chain three correct links in a row to light up a gold halo that boosts your score.

Long-term progression
- Fewest moves and fastest time are tracked across all your wins.
- Earn one math badge for every ten successful challenges.
- Collect five badges to unlock the formula handbook, a personal collection of the equations you have proven.
- A daily challenge serves a fresh seeded puzzle each day.
- After three wins in a row without any mistake, an advanced mode unlocks with powers, roots and double scoring.

Everything runs entirely on your device. There are no accounts, no sign-in and no network connection required. Sound effects can be toggled in settings, and all progress can be reset at any time.

NimbusArc is designed for students and casual learners who want a quiet, focused way to keep math intuition sharp during a short break.
