Deltadle

Deltadle was made in 2025 by BruhOliverLol and is hosted on Neocities under a Creative Commons licence. It is not affiliated with Toby Fox. The site is styled after the game itself, with the pixel heart in its logo and a row of red hearts for your tries.

On the Solo board you get five tries, shown as hearts. You type a character's name and press Guess, and the table fills a row with the character's portrait, class (Lightner or Darkner), pronouns, chapter and type. Green marks a correct attribute, yellow a partial match, red a miss, and arrows say whether the answer's chapter is higher or lower. The Duo board hides two characters at once and shows feedback for both on each guess, with eight tries.

Your streak of days played is shown above the board, there is a code to copy and share, and a Discord server for players. The game can be switched between English, Portuguese and Spanish from the flags on the home page.

It suits Deltarune players who have been through the chapters released so far and know the cast beyond Kris, Susie and Ralsei.

The cast is kept up to date with a public changelog: the summer 2026 updates added characters from later chapters, corrected types and pronouns, and translated the names.
