Getting started
Choose a tier and select Start. The run reveals its counting step; you cannot select an exact step within a tier.
Guests can play. Platform rewards require a verified signed-in account and active player profile.
How to play
- Read Count by and the sequence at the top. Add the step to the last correct number to find the next egg.
- Use Left/Right arrows on desktop. Tap the left or right half of the play field on touchscreens.
- Catch the correct number from each pair. Update your expected value after every correct catch.
- A wrong choice ends the run and reveals the correct next number. Tap the correction screen to see Results; Space or Enter also continues on the web.
- Results show Eggs caught, Highest number and Personal best for that step. Play Again repeats the tier; Change Level returns to tier choices.
TRY THE REASONING
Worked example
Count by fives
- The step is 5 and your last catch is 10.
- 10 + 5 = 15. From a pair showing 15 and 20, choose 15.
- After catching 15, expect 20. These are also 5 × 3 and 5 × 4.
Choose the next term, not just any multiple: 20 is a multiple of 5 but is too early immediately after 10.
Scoring, success and round endings
- Eggs caught counts correct catches. Highest number is the last correct sequence value; four catches at step 5 reach 20.
- Personal best is tracked by counting step. Runs become faster as correct catches accumulate.
- Eligible profiles earn 10 platform coins per correct catch, paid after the final result. Coin effects do not run during catching.

Classroom and home use
Suggested activity: A partner predicts the next term while the player chooses a lane. Swap roles and discuss the correction after a run.
Questions to discuss
- What follows 18 when counting by 6?
- Why is a later multiple not always the next answer?
- How do five catches at step 4 connect to 4 × 5?
This is a teaching suggestion, not an extra mode or a promised learning outcome.
