Word Games - Word Up game

Word Up online game tips:
Use the key letter specified in each round to create as many valid words as you can before time runs out! Place key letters in highlighted boxes for bonus points.

Every game of Word Up has four rounds. In round one you must create as many valid four-letter words as possible within the allotted time. As rounds increase, so do the number of letters you must use to create words.

Each round has a designated "key letter." Use this key letter every time you create a word. For a word to be valid it must be spelled correctly and it MUST contain that round's "key letter". Only valid words will be added towards your score.

At the start of round one, each player has four blank spaces at the top of their board and a full alphabet below. Using the alphabet provided, type letters on the keypad to form valid words. Use the enter key when you are finished typing your word. Use the backspace key to correct any mistakes you make.

Remember, for a word to be valid, it must contain the key letter specified for that round and it must be spelled correctly. In the example below, the key letter for round one is "k", valid words would therefore include, walk, talk, kite, etc.
Bonuses
Each round contains a highlighted bonus box. If you are able to place the rounds key letter into the highlighted bonus box your word will be given an added bonus. For example, the words take and cake would achieve bonuses in the example below.
