Guess the number game (help needed in design)

[diamond_toy]

I need help in designing the logic & block diagram of the circuit which allows a user to guess a randomly generated Decimal number... If his guess is correct, the LED glows green, else it glows red. Another random number is generated ONLY when the user guesses correctly...

I have to make this using combinational and sequential circuits...

What kind of help do you need? Do you want somebody to design it for you, or do you have a specific question?

Yes I am looking for somebody to design it for me. :/
I just don't know where to start from..

To generate a random number, it is common to send fast pulses through a counter. Then stop after a random time.

The 4017 IC would be handy for this purpose since it has ten outputs.

To let a human select a number 1 through 10, arrange 10 switches. An 'AND' gate circuit will tell if he pressed the switch which corresponds to the active line from the 4017 IC.
