Brickdle

Brickdle is a daily guessing game built around LEGO sets. It shows you one official set each day, its product photo and its name, and asks a single question: how many pieces does it have? You type a number and the game tells you whether the real count is higher or lower, so each guess narrows the range until you land close enough to win.

The daily set is numbered (Daily Brickdle followed by a number) and is the same for every player that day, which makes scores worth comparing. The sets come from a list of more than four thousand official sets across LEGO's themes and years, from small Chima or City sets to large Star Wars display builds, so the answer can be a few dozen pieces or a few thousand. There is no limit on guesses: the score is how many you needed.

You do not have to hit the exact number. A guess within a small margin of the true count counts as a win, which keeps the game about good estimation rather than lucky recall. When the daily is done you can keep playing an Unlimited mode that serves random sets.

It suits LEGO fans and anyone who enjoys quick number-estimation puzzles, and it plays in a couple of minutes in the browser.
