Apple Catch Quest
- Catch red, green and yellow apples under the tree.
- Build a bag so P(target colour) matches the mission.
- Walk to the house (left) and press Space or click to deliver.
- Walk to the bin (right) to empty the bag and start over.
- Complete 3 rounds — lowest total time wins!
Paused
Take a break — apples won't fall while paused.
You Won!
Apple Catch Quest: catch apples under the tree, build the right colour chance in your bag, then deliver at the house. Empty at the bin if you need to start over. Lowest total time over 3 rounds wins.
Expected Value Challenge: three options stay fixed for the whole game. Pick one each round to spin — green and yellow on the wheel match the green and yellow payouts shown on each card. Highest total score over 3 rounds wins.
Dice Clear: place all 8 chips on numbers 2–12, then roll two dice. Each roll removes one chip on that sum. Clear the board in as few rounds as possible — lower is better.
Read each page. When a concept finishes, answer the two follow-up questions. They stay on this tab only.
