Arkadium's Codeword is the best free online puzzle game where you can endeavor a new daily word challenge. In this brain-teaser, you must solve crosswords without the usual definitions, but instead decipher them letter by letter.

To make things easier, vowels are used more frequently, so it's wise to first figure out which numbers represent A, O, and E. Additionally, consonants such as S, T, and L are often doubled, which can provide valuable clues to solve word puzzles. As you select a letter on the right, it automatically fills in throughout the grid. You can check your guess on any letter by clicking the ticked sheet icon or use the Eye booster to fill in a cell if you're confused. What makes this game even better is that it's utterly replayable. You can play new crosswords daily for free online and enhance your logic skills or English vocabulary, even if you're not a native speaker.
