Numberle

Numberle was created by the indie developer DDuarte during the Wordle boom of January 2022. It started on GitHub Pages and now lives at numberle.com, where it is looked after by Hey, Good Game, a small studio that keeps daily puzzles running. The site says it keeps the same daily sequence and puzzle numbers as the original, and that other Numberle sites are unaffiliated clones.

The rules are simple. Each guess must be a valid five-digit number. After you submit, a green tile means the digit is in the number and in the right spot, yellow means it is in the number but elsewhere, and grey means it is not in the number. You have six tries, and a new Numberle is available each day.

Besides the Daily puzzle there is an Unlimited mode for extra games that do not affect your streak, an archive of past days that does not touch your streak, statistics with a guess distribution, and a four-board spin-off called Guess 4 with its own daily. An optional free Hey, Good Game account carries your stats and streak across devices and opens leaderboards. The game can be played in English and Spanish, and it has a dark mode and a colour blind mode.

Numberle is free and shows ad banners around the board, most visibly on a phone; a paid Hey, Good Game membership turns them off.

It suits players who like Wordle's logic but would rather think in digits than letters.
