Sedecordle and Duotrigordle
Sedecordle is 16 Wordle boards in 21 guesses. Duotrigordle is the next doubling: 32 boards in 37 guesses.
Both games belong to the same family. You type one five-letter word, and every unsolved board scores it. The names follow the board count: sedecordle is sixteen, duotrigordle is thirty-two. The guess cap in this family is the board count plus five.
What doubling the boards feels like
Sedecordle's 21 guesses leave the same five-guess cushion as Duotrigordle's 37. The difference is memory. Sixteen patterns can still be tracked one by one. Thirty-two means you pin a board, read its keyboard, solve it, and move on, instead of trying to hold every grid in your head. The 64-board game on this site keeps that same plus-five rule and lands on 69 guesses.
Tile colors do not change between these games. A letter that is gold on one board can be gray on the next, because each board has its own answer. That is true at 16 boards and at 32.
