How to play
Feed the machine. Tap the answer.
Choose Start here for +1, +2, and −1 with numbers to 10. Choose Mixed challenge when doubling and working backwards feel comfortable. After a first miss, Capy points to one completed clue without giving away the answer; after a second miss, Capy works through the current equation. Ages 6–8 are a guide; children ages 5–6 may enjoy the starter track with an adult. No timers, no pressure: the capybara is just happy you came.
