One challenge, the same for everyone
Every day there is a new daily challenge. All players get the same setup and play against the same bots, so results are directly comparable.
Afterwards, check the leaderboard to see how your score compares; past leaderboards stay available too.
A few minutes a day
The daily challenge is short enough for a coffee break. It suits anyone who wants a regular puzzle without arranging a game with other people.
How the scoring works
Like every Approx game, each question has a numerical answer and you reply with a range. Narrow ranges that contain the answer score best, and an exact single-number guess earns a bonus. A range that misses scores nothing, so the challenge is in judging how sure you really are.
Build a habit
Pair it with the daily ROX bonus on the home screen for a quick routine: claim the bonus, play the challenge, check the leaderboard.
