Find the Rule, Fill the Gaps
Every sequence hides one rule: add 2, add 10, or count backwards by 5. Your child reads the numbers that are shown, works out the jump between them, and types the ones that are missing. Skip counting becomes a small puzzle instead of something to recite.
Three Levels, One Tap
Easy keeps every number under 20 and hides one term. Medium goes up to 100, counts up or down, and hides as many as three. Hard reaches 1000 and shows only the first two numbers and the last, so your child builds the whole middle of the sequence. Instant feedback, no timer, no account.
