Play RNGdle in Your Browser

RNGdle background

RNGdle's changelog records its public launch on 5 December 2025. Later updates have added and retired badges, introduced favorite badges and profile options, and added a settings page. The game has a leaderboard and a Discord community where players share their rolls.

Unlike most daily "-dle" games, there is no puzzle to solve and no skill involved; the entire game is a single roll. Several unofficial copies with different rules use similar names, but rngdle.com is the original site described here.

How to play RNGdle

Each day you press a button to roll one number. The game then checks it for properties such as palindromes, prime numbers, repeating digits, well-known meme numbers and mathematical sequences, and each match earns a badge and EP (entropy points). Badges are graded from Common, found in more than 10% of rolls, up to Mythic, rarer than 1 in 100,000. Your total EP ranks the roll against all possible rolls in tiers from Trash (bottom 1%) to Mythic (top 1%). Over time you build up a badge collection and compare results with friends.

1. Open rngdle.com and press the roll button to get today's number.
2. Look at which badges your number earned and its overall rarity tier.
3. Share the result with friends or check the daily, weekly and all-time leaderboards.
4. Come back the next day for a new roll and add to your badge collection.
