How to Play
In a nutshell, AVRSimon gameplay is as follows:
When you first power on the game, a start-up tune will welcome you. Press any of the pushbuttons to
start playing.
The game will generate a sequence of lights/sounds that you are to repeat, first starting with a single
element. After the sequence has been presented, simply press the button(s) corresponding to the LED
that was illuminated and repeat the pattern. The sequence length will increment each time you
successfully repeat the pattern, making the game increasingly more difficult as you go. The maximum
sequence length is 255.
When your game is over, a short tune will be played, the correct LED in the sequence that you were
supposed to enter will be illuminated, and then your score will be given by a series of blinking LEDs. The
green LED corresponds to ‘hundred,’ the red LED to ‘ten,’ and the blue LED to ‘one.’ For example, if you
failed after a thirteen element sequence, the red LED will first blink once and then the blue LED will blink
three times.
AVRSimon has a few optional twists to make gameplay more fun and interesting for advanced players.
These special modes are selected by holding down one the pushbuttons SW1-SW4 while first turning on
the game (multiple pushbuttons can be held down at one time to create various combinations):
SW1: No Sound/Quiet mode
No sounds are generated while in this mode, making it perfect for gameplay while late at night, in a
library, conference session, or classroom.
SW2: Fast mode
This mode increases the speed of which the LED sequence is played by three times and reduces the
length of time allowed for you to repeat the sequence. Normally, you have five seconds to make a
decision for each move. In fast mode, you’re only allowed two.
SW3: No LED mode
No LEDs are illuminated while in this mode. You’ll have to repeat the pattern based on sound alone.
SW4: Reverse move
This mode operates like a FIFO (First In, First Out) stack in which you have to replay the sequence in
reverse order (instead of repeating the exact order that the game presents).
To revert back to game’s normal mode of operation, simply power cycle the unit.
