3 Lucky Monkeys

Hold and Respin, or 'Hold & Win', is one of the most popular core bonus game mechanics in modern slots. The essence of this feature, unlike traditional free spins, is to 'Hold' bonus symbols on the reels and 'Respin' the remaining empty spaces to fill up the screen. This system was popularized worldwide through 'Money Train 2's' 'Money Cart Bonus' and is the foundation for numerous developer-specific brand features like Wazdan's 'Hold the Jackpot™' and Playtech's 'Fire Blaze™'.

Full Screen Bonus is a special payout rule that awards an additional bonus (usually a multiplier) on top of the standard prize at the visually most satisfying moment when all positions on the reels are filled with a single identical symbol. The core of this feature is that it is distinguished from a regular high-payout win, as it is an 'achievement-based reward' given for accomplishing the special condition of 'filling the entire screen'.
