here is a electronic dice circuit from crocodile clips but the power is from rails and not a 9v battery.
i have tries numerous ways to try and get it to work with a 9v battery even adding extra components, but either some of teh components blow or the LED's dont light up bright enough if at all!!
Use CD4XXX series logic. It will run off 9 volts, but it won't drive LEDs very well, so you will probably need an emitter follower between each logic gate and the resistor for its LED. If you want to run the LEDs at 10ma, change the resistors to 620 ohms. You also will need a 100k resistor to GND on the EN input of your counter.
Ok first to answer your question the reason your leds are not lighting up is because CMOS non-inverted outputs (the gates without the little circles on the ends) do not have the current output. Only ever use a CMOS non-inverted outputs to drive the input of another gate or transistor.
comment on design:
You do not need the logic gates at all, one chip is enough to do this project. A binary ripple counter can give you outputs to drive LEDs and has an inbuilt clock. This would mean if you roll a 3 then 3 LEDS will light up if you just want one LED at a time look to a decade counter.

Please follow the others suggestions above but also consider that one of your problems might be incorrect connections of the components. You might have some short circuits somewhere. Check your construction carefully.
