Game: Farkle Pro

Farkle Pro is one of many Facebook apps that lets you play the slightly obscure dice game Farkle online. Playtika's iteration is easy-to-use, runs well, and features robust matchmaking. It also explains the rules, which may be unfamiliar to many players. Farkle is somewhat similar to the classic Hasbro dice game Yahtzee, but the rules are a bit simpler and there's a big emphasis on betting.
