The program can be controlled by mouse, keyboard or concept keyboard. The selection of input device, sound level, difficulty level and word list can all be made off the main menu - which is obtained by pressing the middle (*MENU*) button over the main program window.
There are three choices potentially available for input. These are mouse, keyboard or 'concept keyboard' (if an appropriate I/O podule is present).
There are seven word lists supplied with the program. These are Bodybits, Clothing, Countries, Creatures, Food, Household and Sport. You can choose to have your words come from one of these lists by selecting the desired list from the menu. The default option is 'random' which allows the computer to choose the word from any list on a trial by trial basis.
There are four specific levels of difficulty: *Easy*, *Moderate*, *Hard* and *Very Hard*. These levels vary in the number of letters the words may have. The easier levels use shorter words.
To play the game using the mouse, you first click on the 'Start' button by moving the pointer over the 'Start' box and 'Selecting' by pressing the left (SELECT) button on the mouse. If using the keyboard press the SPACEBAR. Because the program is trying to continually match the difficulty of the task to your performance you may find that the level may vary quite a bit. This is no cause for concern.
