Word Scramble & Unscrambler
Turn a jumble of letters into every word they make, with wildcards and filters, or play the daily scramble.
Word Guess
Guess a hidden word one letter at a time. A correct letter reveals every place it appears, a repeat costs nothing, and every wrong letter drains the signal beacon. Five presets including a hand-picked kids list and a daily word.
Letter Grid Hunt
Trace words through touching letters and take as much of the grid as you can. A square cannot be reused but a letter can, rare letters are worth more, and every word you missed is revealed at the end.
Word Ladder
Turn one word into another one letter at a time, with every step a real word. Every pair is checked to be reachable before you see it, and par is a measured shortest route rather than an estimate.
Cryptogram
Decode a substitution cipher in a clean letter-mapping workspace. Every passage was written for Zerdly rather than quoted, no letter ever stands for itself, and Strict Mapping changes the rule instead of the size.
Letter Hive
Build words from seven letters, always using the core in the middle. Letters repeat as often as you like, every hive holds at least one word using all seven, and the scoring was counted from the dictionary rather than chosen.
Category Sprint
One letter, several categories, one answer each against the clock. Some categories are checked against a real list and the open ones are on your honour — and the game always says which is which.
Trivia Arena
One question at a time, four answers, and an explanation for every one. Every question shows where its fact came from, and the wrong answers are provably wrong.
Word Chain
Every word starts with the last letter of the one before it. Keep the chain going alone, against the clock, or against an opponent that answers back.
