Hello, Sandboxerinos.
If we all pitch in and offer advice as a community, I'm sure we can create a comprehensive guide on how to play each role there is.
If someone has already explained a role here, whether in detail or just with a hint, feel free to offer your own explanation too. The more advice the better.
Here are a few hints to get us started:
Deputy/Sniper: Look at all the people in the town and decide who you don't like, based on their avi, manner of typing, name, or past experiences with this person. Then shoot that person. Whether you are sniper or deputy doesn't matter, this is very helpful to do. Nitro's Pro Hint: Also consider playing a game of 'next person to speak gets shot'.
Cop (any): On day one, announce your report immediately. Based on this, even without your sanity, the town can decide who to lynch. If you didn't get a report, whether because you are lazy or were blocked, still announce that you are a cop and didn't get a report. This is vital information.
Fool: Let everyone know that you are fool. If you are polite about this, the town will understand and lynch you. If you try to subtly make yourself look like mafia, town will realize you are being a sneaky fool and will not lynch you.
Mafia in general: Don't talk during the day, except with 'lol' or 'yeah'. If there is a non meeting member, do not attempt to discover who he is and do not contact him. When the tree, celebrity or designated clear asks for claims, you have several, ironclad options to secure your safety:
1) Say you'll be brb, and watch patiently until you can hammer. The clear will not suspect you.
2) Claim bulletproof, bleeder, ghoul or lightkeeper. There is no way of proving you are these roles, so this is a pro strategy that will make you win every single time.
3) Give him the runaround, talking about how claiming is for losers or how you're 'nothing to worry about'. The clear will have no reason not to believe this, and in fact, this may even save your partners from having to claim.
I hope that together, us Sandboxerinos can create a complete guide for each role.
