Compdle

About Compdle

Compdle comes from Clector, a site that tracks eBay sales of football, basketball, baseball and hockey cards. The name borrows from comps, the recent comparable sales that collectors look up before they buy or sell, and the game turns that habit into a quick daily quiz.

Each day's puzzle is dated and shared by everyone. You get ten match-ups of two cards each and pick the one whose average sale price over the last 60 days is higher. Each round has a 12-second clock, so there is little time to reason about print runs, grades and parallels; you go with what you know about the player, the set and the market.

You can play once a day, and the result is scored against that day's puzzle. Playing needs no account, but signing in puts your score on the leaderboard. A countdown on the page shows when the next puzzle arrives.

It suits card collectors and flippers who follow prices, and sports fans who enjoy higher-or-lower games and want one about the hobby side of sport.

How to play Compdle

1. Open Compdle and start today's puzzle.
2. Look at the two cards in the first pair: player, set, grade and parallel.
3. Pick the one you think had the higher 60-day average sale price, within 12 seconds.
4. Repeat for all ten pairs.
5. See your score for the day, and sign in if you want it on the leaderboard.

Tips

• Graded copies, low-numbered parallels and rookie cards usually beat base cards of the same player.
• A modern star's base card can lose to a numbered parallel of a lesser player; check the serial number first.
• With only 12 seconds, decide on the one detail that matters most rather than weighing everything.
• Recent hot streaks and injuries move 60-day averages, so news counts as much as career value.
