How to play Castle Builder II

Because Castle Builder II is high volatility, wins are infrequent but can be large. Use smaller bets relative to your bankroll so you can ride out longer dry spells, and set a loss limit before you start. Chasing losses with bigger bets is the fastest way to bust against a fixed house edge. No betting system overcomes the house edge — play Castle Builder II for entertainment within a budget.
