The bonus features on offer are uniquely tweaked versions of innovations you’ve already seen, with small changes that make big differences.
Coin Booster / Collect
When a special 1UP symbol appears, it will increase a win multiplier that has its value displayed in an odd-looking contraption on the left of the reels. The multiplier starts at 1x and increases by +1 whenever the symbol lands, up to a maximum of x10. This feature only kicks in when certain symbols make an appearance.
When Coin Symbols appear on the same spin as the Collect Symbol, the Coin values will be multiplied by the Coin Booster and added to your balance, also resetting the booster multiplier to 1x.
Land 3 scatters on the middle 3 reels to get to the Bonus Selector screen, where you have to choose from three options. You can have 3 free spins where all 4 corners can turn wild, 6 free spins where 3 corners can turn wild, or 9 free spins where 2 corners can turn wild.The Lock and Load feature activates on every free spin, and you can claim up to 3 extra free spins when you fill the entire screen. Special multiplier symbols that only appear during the bonus round will upgrade your existing multiplier that is carried over from the base game. If you want to get right into the action, The Bonus Buy feature lets you gamble for instant access to free spins. You can choose from a 10% to 90% chance to trigger the bonus round. The better your odds, the more you pay in. You could also exchange an amount worth 100x your stake for immediate access.
You need to land one heart symbol on all five reels to trigger the Heart Bonus, which is a hold-and-win-based feature. You will begin with 3 bonus spins and an empty grid where the spin recount resets each time a coin symbol lands. The coin symbols will become sticky when they appear, and the feature will end when you run out of spins or when you have filled every position on the grid.
If you manage to fill the grid, each Coin Symbol will transform into a 50x symbol, but if the round ends normally, you will receive the combined value of the coins in view, with the Coin Booster multiplier applied.
Playing the Game
Getting started with Pile ‘Em Up is as easy as inserting a coin into a n arcade game. Just choose your bet level, check out the quick spin and sound options in the menu, and then press spin and you’re on your way. You can choose up to 100 spins on autoplay and this game is suitable for all levels of experience, although if you haven’t experienced a hold-and-win feature before there may be a slight learning curve when it comes to the heart bonus.
Pile ‘Em Up slot is a quirky and engaging title with exciting winning opportunities. The slot’s video game-style theme is simple but effective, with bright, cheery graphics that create an upbeat atmosphere. The base game is action-packed, and I enjoyed gathering hearts and boosting the multiplier with coins while I waited to trigger the bonus features.
The collect feature got me some decent wins, but things really took off with the free spins and heart bonus that delivered the most rewarding moments. You can win a maximum of $225 000 from a single spin, and this title will awaken your inner child. For more videogame related titles with unique bonus mechanics, you’d be hard-pressed to find anything better than Street Fighter 2: The World Warrior or Monster Blast.
