Find out more about this slot in our review below.
Overall theme
This game from Leander free slots uses the classic and beloved theme of fruit. It is how slots started out, with a simple design and allowing you to focus on what the game is about.
The background of the slot makes it look like you are on a dance floor illuminated in pink and blue. This appeals to the more futuristic nature of the theme, although the symbols are old-school. The soundtrack has a smooth jazz vibe.
You can play another game with a similar theme in the form of the Leander's Taxi Leander Slot. This is also available to play for free in demo mode here at Slots Temple.

Starstacks RTP and variance
Unlike many classic-themed slots, Starstacks not only has high variance but high variance at the very top of the scale. This means the wins may be higher but you are going to need a lot of patience to wait for them to roll in.
The RTP of Starstacks is where we hit our first snag, as it is slightly below the industry average. Sitting at 95.79 per cent, we would have loved to see this bumped up slightly to hit the average rate of 96 per cent.
How to play Starstacks
You can learn how to play this slot and how the controls work by reading the following section:
- Set your bet by clicking the coin button. This will display a full betting menu from which you can choose an affordable amount.
- Click the large spin button to spin the reels once at your chosen bet amount.
- The hamburger menu is where you can change your sound settings and view the slot information/game rules.
- Always play slots responsibly, taking advantage of the self-exclusion and timeout functions if necessary.
Bet sizes & paytable wins
There is a good range of bets that will suit everyone, from those playing on a budget to the high rollers with cash to spare. The minimum you can bet per spin is 0.50 coins and the most is 500 coins. You should only spend what you can afford on slots, so set yourself a realistic budget and stick to it.
Symbols have to land in combinations of three to five of a kind across an active payline to award a payout. The top multipliers available are:
- Cherries, lemons = 100x
- Oranges, grapes = 150x
- Watermelon = 200x
- Bar = 250x
- Bell = 300x
- Seven = 500x
- Diamond = 1,000x
Starstacks bonus features
Wild symbol
The wild symbol feature in Starstacks is where the stacked wilds come in, potentially making a huge impact on your game. The wild will substitute for other symbols on all 50 paylines.
The wild symbols have the potential to bring in multiple wins at the same time, as they can land on so many paylines; however, they will only appear on the first, third and fifth reels.
Free spins
You have to land scatter symbols on the reels to trigger the free spins round. Players will receive 12 free spins with multipliers, which means you could double all the wins in the round. You can also win up to 100x your bet when there are three to five scatter symbols on the reels. These won’t retrigger the feature.
Star card
The last feature of the game is the star card bonus, which has the potential to award you mystery cash prizes. You need to land bonus symbols to trigger this round, which can only land on the second, third and fourth reels.
This round is a pick feature and has the potential to be very valuable. You choose from the star cards shown on the screen and the revealed multipliers will apply to your bet from the round that triggered the feature. The round will come to end once all ten cards have been picked or when you find the collect card.
Conclusion
Starstacks may not look like much but the features make it a really entertaining slot to play. It is more than capable of holding a player’s attention with its fun theme and the promise of great prizes; however, be aware that RTP and variance combination makes payouts hard to come by.
