Werewolf online is currently the most popular mafia-like online game on android, however, a quick look at the role setup tells you that you should avoid it like the Black Plague.
The game uses a known, predefined role setup.
Town:
Alignment detect cop, Rolecop, Detective, Two-shot Daykill Vigi (that reveals on first shoot), A medium that can REVIVE and talk with dead players during night (Medium), One Jailer, One Bodyguard, One Docto- ah isn't that too unbalanced?
You don't need to know the rest of the role setup to know it's unbalanced. The cops reveal on Day 2, and reveal their results, with a "doc on me", if a cop has found a werewolf, the town says "vigi shoot!", and the werewolf dies, no social deduction and deception at all. This continues on until the rest of the game. The sad thing is people still find this game fun, even if town has a 95%+ winrate. The worst rep I have seen that this game get is that it's a "Town of Salem Clone". Hey! Please know the origins, Town of Salem isn't the first mafia.
So, you made new account to trash some shitty online game here? I can see how you can be upset cause you can't win as werewolf there, but I doubt anyone here is interested in that. You should head to their forums and tell them your heartbreaking stories about your lost games in their game
Werewolves seem to win a fair number of games, I don't know if it's 50%, though. There can also be a fool (aka tanner or jester), headhunter, and/or arsonist who are self-aligned.
