The Casino Boost feature enables you to boost your winnings during the boost period by the indicated percentage. If you have an available Casino Boost you will see a banner on the start page, which shows more details about the boost (boost percentage, time until the boost expires, eligible games).
The active boost period will start with the first spin on any of the eligible games. Upon activation of the boost, a timer will start ticking, and all wins you score within the boost period will be taken into account for the calculation of the boost reward.
The timer will stop when it reaches 0 or when the maximum boost amount is reached.
Player A has a 10% casino boost on any slot game available. The boost duration is 2 minutes and the maximum boost reward is 10 mBTC. Player A plays on a slot for two minutes and wins 30 mBTC. Player A can now claim his boost reward with the value of 3 mBTC (30 mBTC * 0.1 = 3 mBTC).
Player B has a 20% casino boost on any slot game available. The boost duration is 3 minutes and the maximum boost reward is 5 mBTC. Player B starts playing and immediately wins 100 mBTC. Because the boost amount has reached the 5 mBTC limit (100 mBTC * 0.2 = 20 mBTC), the timer stops immediately. Player B can now claim the maximum boost of 5 mBTC.
