Eterna vs Letter Lattice

Eterna is a citizen science game where players learn to design RNA molecules for medical research by solving puzzles. Complete introductory puzzles to unlock lab access and participate in challenges where you can invent medicine!

Letter Lattice combines the best parts of anagrams and crosswords into challenging word-weaving madness! How do DOG and CAT relate to each other? What about GUITAR and MELODY? I made this game as an appreciation for the intertwining nature of words in the English language. Most word games have you searching for anagrams within a single word. In Letter Lattice, puzzles use anagrams as connectors to morph from one word to another, each word you find being essential for solving the rest of the puzzle. — SOMETHING FOR EVERYONE — Whether you’re better at anagramming or solving crosswords, there’s something that suits you in Letter Lattice. With hundreds of handmade puzzles, beginners can become experts, climbing their way up from “Easy Threes” to the dreaded Super-Skull puzzles. — SOMETHING FOR COMPETITORS — “Arcade Mode” pits you against procedurally-generated puzzles of increasing difficulty until the clock runs out. Race to solve as many puzzles as you can, gaining bonus points for finding rare words. Can you reach Milestone 5? What about Milestone 10?! — SOMETHING FOR ACHIEVERS — Unlock achievements by completing daily puzzles, solving clues, and zooming through Arcade Mode. As you progress, earn vibrant, hand-crafted color palettes that change the look of the entire game. From the earthy greens of the “Sequoia” palette to the rich pastels of “Coral,” there’s something here you’ll love. —ALL FEATURES (for FREE!) — - 20 Puzzle Packs (with 400+ crafted puzzles) - Infinte Procedural Puzzles in Arcade Mode - New Puzzles Daily! - Statistics and Achievements to track progress - 8 Beautiful Color Palettes — FULL VERSION - 10 More Puzzle Packs - More Arcade Plays - Access to the ever-growing Daily Archive - 4 Additional Color Palettes - Day/Night Palettes, effectively adding 12 palettes! ~ A note from me ~ — I started developing Letter Lattice after playing these puzzles in a notebook on New York subway commutes. I enjoyed the paper puzzles so much, I spent over a year building the optimal digital interface for the puzzles to exist within. Along the way, I discovered so much about the English language becoming entranced by the similarities between words I had once thought were very different. I began to appreciate even the simplest of words and how they relate to others. If you have read this far, I hope playing Letter Lattice will help you find this same magic that made me passionate to develop this game. ~ Ethan
