Need Advice on Casino Games

[mr_wexer]

We're currently considering developing a casino slot machine game for iOS and Android and were hoping to glean some info from the TA community. Especially anyone who has worked on this type of slots game before.
Lucky Gem casino on Facebook is similar to what we're aiming to do.

- These games appear to use the same generic slot mechanic no matter who releases the game. Does anyone know where the best place to go to get the opensource code for this? We do not want to reinvent the wheel for this.

Any advice at all on the dev of these types of games would be very helpful
