Jack's Beanstalk Bonanza

A Collection Meter is a system where a progress bar or gauge (meter) is present on the game screen, which fills up each time the player collects specific symbols or performs certain actions. The core of this feature is to provide the player with a long-term goal that goes beyond the success/failure of a single spin. When the meter is full, an instant prize or a special bonus is awarded as a reward. This provides players with a growth-type fun, similar to 'leveling up' or 'completing a quest'.

Bonus Buy is a feature designed for players who dislike waiting indefinitely, allowing them to pay a set multiple of their bet (usually 100x) to instantly start the game's highlight: the free spins or bonus round. The core of this feature is the concept of 'buying time' by skipping the tedious base game. It is one of the most beloved options for modern slot players who seek high risk and high return.
