Memory
Reveal pictures to find pairs in as few tries as possible.
Move the cursor with the 2 (up), 4 (left), 6 (right), and 8
(down) keys.
Press the 5 key to reveal pictures. Press the # key to jump
right over revealed pictures or move from bottom right to
top left. Press the key to jump left over revealed
pictures or move from top left to bottom right. Once
found, pairs stay visible.
Snake
Feed the snake with as many goodies as possible and
watch it grow. Use keys 2 (up), 4 (left), 6 (right), and 8
(down) to turn the snake toward food. The snake can only
turn 90 degrees at a time.
The longer the snake's tail grows, the higher the score.
Using a higher level of difficulty increases the snake's
speed but also increases the point value for each goodie.
If the snake hits its own tail or the surrounding wall, the
game is over.
You can also try using keys 1 (up and left), 3 (up and
right), 7 (down and left), and 9 (down and right) to
control the snake's direction.
Logic
Find a secret combination of figures. Available figures are
shown at the top of the display before you accept the first
guess row. Use the 2, 4 and 8 keys to move the cursor and
the 5 key to select the figure.
To copy a figure from a previously accepted guess row,
start scrolling with the 4 key, move the cursor to the
desired figure in the normal way and accept the selection
with the 5 key.
Once you think you have the right combination, press the
ó key. The result is presented as a set of marks over the
row. A correct figure in the right place gives a full mark;
a correct figure in the wrong place gives a half mark.
The game ends when all the figures are correct and in the
right place.
