Useful to know
Does this game save or upload my play?
Your round stays in browser memory. No gameplay is uploaded. Eligible solo final scores can be saved only after you enable Save personal bests on this device. The toggle starts off on each visit; turning it off erases Game Kit scores. Charades and local two-player scores stay in the session.
Can I play without a time limit?
Choose practice or untimed mode where offered. You can pause any running round. Hiding the browser tab pauses and hides the board; returning requires Resume. Every session remains bounded to four active hours.
Are device scores a public leaderboard?
No. They are optional, self-recorded scores in this browser. They are separated by game rules and relevant settings. No Kenya-wide, worldwide or independently certified rank is claimed.
What are the current limits?
10–30 cards; Starter/Practice/Challenge ranges; nonzero integer division. Sprint lengths 30/60/120 seconds, or untimed. No curriculum-grade claim.
Do I need to fill in the settings before I can play?
No. Quick play starts a complete built-in round with sensible defaults. Open Customise this game only when you want to change the available settings.
How does automatic continuation work in this game?
Type your answer and press Enter or Check. Read the corrected equation; the next card follows automatically. Unfinished numbers are never auto-submitted. Use Stay on this answer or Pause when you need more time, or turn off automatic continuation in the game preferences. Continue now remains available.
Where are my files and inputs processed?
Play stays in this browser, with no account or remote leaderboard. Personal bests are saved only if you enable that option. Reset clears the round; use Erase device scores to remove those optional records from this browser. Private prompts and answers are excluded from the shared summary actions.
