About CCUdle

CCU means concurrent users: how many people are playing a game at the same moment.

A daily guessing game about Steam concurrent users (CCU). Two games, one question: which one had more people playing at once? Ten pairs a day, getting closer as you go.

How to play

Each day has ten pairs. Pick the card you think wins; the answer and the margin show right away. The first three pairs are far apart, the middle four are closer, and the last three are within 1.5× of each other. Everyone gets the same ten pairs, and a new set starts at midnight in your time zone.

Your results, streak and score history stay in this browser. Practice plays random pairs that don't count. Keys: 1 or ← for the left card, 2 or → for the right.

Live

Live compares each game's peak on one UTC day: the most people playing it at the same moment, from hourly samples of Steam's own player counts. Because players around the world start each day at different times, a puzzle uses the day that finished two days before it, and the question names that day.

All-Time

All-Time compares the highest peak CCUdle has recorded for each game since it started tracking. It opens once there are 30 days of history.

Where the data comes from

Player counts come from the Steam Web API. Genre and price model come from SteamSpy. Only games on Steam are included, so a game's players on other stores and consoles don't count. CCUdle isn't affiliated with or endorsed by Valve or Steam. Steam is a trademark of Valve Corporation.
