Word Hurdle has extremely basic rules and is suitable for players of all ages. You need not rehearse before playing; you may begin the game instantly.
The number of squares in the game's interface correlates to the number of letters in the word you must interpret. Unique to this game is the ability to test an endless amount of wrong words and correct them until the correct phrase is discovered. The correct letter and location will be displayed in blue if your guess is correct. The correct letter will appear in yellow if it is in the incorrect location, and in gray if your estimate is completely inaccurate.

Unusually, the colors you mistakenly estimate will always appear on the screen of the keys in word hurdle. After guessing all of the columns, you've colored all of your keyboards.
