How to play Costcodle
- Look at the product and its pack size.
- Type a price in dollars and submit.
- Arrows tell you to go higher or lower, and the color shows whether you are within 25% of the price.
- Land within 5% of the real price in six guesses to win.
Tips
- Think in bulk: Costco sells large packs, so price the whole box, not a single item.
- Use your first guess to bracket the price, then halve the gap with each guess.
- Once you are inside the 25% band, move in small steps instead of big jumps.
