On-Words is a word game involving spelling, counting, and phonetics.

Students play in groups of two or three. The first player uses the digit cubes to set a Goal, which specifies the required point value of the solution. Soultions may be either a single word (point value = the sum of all the letters in the word) or a network of intersecting words (point value = the sum of the all the letters in every word in the network). Each player must find a Solution using the letter cubes rolled to form a word, or network that has the point value as the Goal.

Phoentics cubes are used as constraints on the sounds in the words in the solutions.

Players take turns moving to the Required, Permitted, or Forbidden sections of the mat. Any letter cube moved to Required must be used in any Solution; any letter cube in Permitted may be used; any letter cube in Forbidden may not be used. A phoentics cube in Required means that at least one word in the Solution must have the spund represented by the cube; a phoentics cube in Forbidden means that no words in the Solution may have the sound represented by the cube. Thus the players themselves shape the Solution, forcing one another to create new Solutions in response to moves.

At any point a player may challenge the last mover, if they feel the last mover has made a mistake. There are three types of Challenges.  A-Flubmeans that the Challenger can make a Solution using the cubes in Required and Permitted and one more cube from Resources. P-Flub, or Challenge Impossible means the player believes the Mover cannot make a Solution using the cubes in Required, Permitted, and Resources. C-A- Flub means that the Challenger believes that the Mover, or some previous mover, missed an A-Flub.  After a challenge, at least one player must show a correct Solution on paper. The scoring goes like this:
     The player who wins the challenge scores 10 points.
     The loser of the challenge scores 6.
     If there is a third player, he must side with or against the Challenger and scores points depending upon that decision.

A game may also end in a Forceout.

On-Words is an excellent way to help build vocabulary for young students.
