I would like to add this if you like more.

Opensource dice script:
- https://github.com/Bitsino/BitsinoDice
- https://github.com/Bitcoin-Dice/bitcoin-dice.github.io = this one is the oldest one dice script that needs moneypot.
- https://github.com/Bitlits/Bitcoin-Casino = This one includes other games like slots and lottery.
- https://github.com/coinables/Bitcoin-Faucet-Dice-Faucet-Box =Since your plan is to implement it on your faucetbox this might the exact script for you.

Like the above said it's not always safe to use other scripts but if you have the knowledge to check the script. Always make sure to check them for backdoors.
