Make it possible for the user to choose between head or tail.
Since the current smart contract, doesn't store this information into the blockchain, we need to store the the user choice somewhere else.
Having a dedicated backend is not currently an option because it would involve more maintenance and more restrictive requirement. For instance it won't be possible to host the backend on GitHub pages.
We could think of a thirdparty DB storage service, like Firebase storage, but that means adding a new middleman.
The other option is to store the info browser side, e.g. session. This is most likely what we would try.
If the user bet choice can be found in its session, we display it, otherwise we default to e.g. Head.
It means the user could see different head/tail results from one browser to the other, but the win/loss would always be the same. So this probably needs to be explained in a note somewhere.

You may use IPFS for storing the choice of the user and then tell to the to the smart contract to look inside to IPFS.
If you don't know about IPFS i would suggest to look in here
Also you can see this example this

I really like your project and I look to help how ever I can. Hope it helps

Thanks for sharing. Yes I like what IPFS can do, but it might be a bit overkill for our use case.
Also someone from Reddit suggested using another smart contract to store meta info https://www.reddit.com/r/etheroll/comments/aa3hmj/we_can_build_any_chances_based_games_on_etheroll/ecqmxqg
