# NUMBER STRIDE

Carry a number through sixty fixed runner stages, each with twenty to sixty three-way calculation gates. Change lanes using Left/Right arrows or touch swipes; the gate in your lane applies automatically. Negatives, powers, roots and reversals reward looking ahead. Finish at or above the target. The run never stops between gates; pause fully covers the track. Local progress and undo, sound off by default.

arithmetic runner browser game; three gate math puzzle; number game with powers and roots; long number puzzle local save.

### Which devices are supported?

desktop, tablet, mobile.

### Can friends play together?

Single player. No human multiplayer or online multiplayer.

### What are the controls?

The number runs forward continuously. Left/Right arrow keys or touch swipes change one lane; the gate in that lane applies automatically. Z undoes, R restarts, P/Esc pauses, M toggles sound. Phones are portrait-first with landscape support. Pause fully covers numbers and formulas; the route preview does not pause movement. Hitting a marked undefined/out-of-range gate ends the run, without NaN or automatic lane correction. Zero and negative numbers otherwise continue. Finish every gate, then final displayed value >= target wins, including a tie. Exact integer-cent arithmetic rounds half away from zero to two decimals after every operation; display and actual inputs agree. Sixty fixed stages, twenty to sixty choices each. Local records and stable run saves after each gate, no accounts, gameplay APIs or cloud save. Every document starts muted; language follows the portal URL only.

### Is it free, and does it require an account or download?

Free browser game, with no sign-up or installation.

### How do language and sound work?

English and Simplified Chinese. The portal passes the selected language; English is the default and games have no separate language selector. Every load starts muted; sound requires explicit opt-in.
