Zol's Echo Same word hunt. Half the clues.

The rules

• There's a hidden word of a fixed length. Type any real word and submit.
• Instead of colouring each tile, Echo gives you counts: how many of your letters are in the right spot, and how many are in the word but somewhere else.
• That's it — you're never told which letters those are. You have to reason it out by changing one thing at a time and watching the numbers move.
• Line up the word before your guesses run out.

It's the same idea as a colour-clue word game, with the training wheels removed — the hardest word hunt in the collection.

Choose your difficulty

• Easy — unlimited guesses, and a hint can hand you a correct letter in place when you're stuck.
• Medium — a generous guess budget.
• Hard — a tight budget; run out and it's a loss.
• Zolified — the counts collapse into a single "how many are right" number, hiding even more, and a 30-second clock reveals one true letter — at a rising cost — if you stall.

Change one letter, watch the number move, and you've learned something. That's the whole game.

Three ways to play

The Daily is one shared word for everyone. Free Play is unlimited rounds at any difficulty. And Versus is a duel: you each pick a word for the other to hunt down, then set to work — the sharper deduction wins.
