Kalamba Games released Joker Spark 7s in the fall of 2024. This is a retro slot with a small field, fixed paylines, additional multipliers and jackpot analog. They added the trademark 4-level HyperBet: the gambler can choose how many special symbols are involved in the game. The slot is designed beautifully, modern, though not flashy - but this is a plus: the design does not distract, does not cut the eye and does not interfere with the game. Those who are particularly lucky - can fly payout of x10000: this is the maximum possible for the slot.

The Joker Spark 7s pays on 10 fixed lines. The line must include a minimum of 3 characters from left to right as standard. The field in the slot is small and stylized under the old slot machines. Its size - 5x3. For such a small field on it falls a lot of signs: 9 simple and a few more special, which are added special properties. Stakes are accepted in the amount from 0.05 to 100. Winnings are limited to a multiplier of x10000, which can be caught for 12 Cashpot symbols on the reels.
Gambler can choose 1 of 4 HyperBet levels (the buttons for this are under the field), which determine the number of special symbols participating in the game.
Here are the special symbols involved in the game and their meanings:
Multiplier Wild. Performs the standard function of Wild - that is, it is included in any payline, on whichever side (or inside) of it does not appear. It also carries an additional multiplier of x2 or x3.
Multiplier Bar and Multiplier Seven. There are 2 more symbols with additional multipliers, only already fixed x3.
Cashpot and Super Cashpot. Carries a random multiplier (Super has a higher multiplier than the regular Cashpot). It will be paid out when 5+ of these symbols appear on the field.
Bonus. Serves as an activator for free spins.
The bonus functionality of the slot is small. It includes:
HyperBet. There are 4 levels in the slot. Between them they differ in the minimum bet (0.05, 0.25, 0.50 and 5.00) and the set of characters on the field. The higher the level - the higher the minimum bet, but also the more special symbols are involved in the game. Levels are selected by 4 buttons under the playing field. In the first level (left button) only Multiplier Wild is involved. In the second round, Multiplier Bar and Multiplier Seven are added. In the third round, Cashpot is added, and in the most expensive fourth round, Super Cashpot is added.
Buy Bonus. You can buy free spins here anytime.
The appearance of 3 Bonus symbols on any cells triggers 10 free spins. The only difference from the simple game is that each Bonus symbol will be added to the counter with 3 empty slots. When they fill up, the gambler will be added 3 more FS. Free spins can also be bought in the Buy Bonus at the bottom left. There is a package of 10 or 15 spins to choose from.
The round starts at the bet and HyperBet level that was in effect when activated.
There are no regular jackpots in the Joker Spark 7s, but instead there are separate payouts for the appearance of 5+ Cashpot symbols on the field. The winnings for these are listed above the field.
Five symbols will pay x10 of the bet, and 12 will pay x10000. Therefore, it is profitable to play at HyperBet levels 3 and 4.
The characteristics on which the return on bets depends in the slot are set as follows:
The slot's RTP depends on the player's region and which HyperBet level is selected. Level 4 has an RTP 0.16% higher than level 1. An even higher return percentage is set for purchased freespins.
The volatility is 8/10. That's pretty much the golden mean. The slot will rash often, but mostly a little bit at a time. You won't have to wait too long for big payouts either, though.
It is impossible to cheat or some strategy to beat the random number generator. And it is he in slots is responsible for the result of each rotation. HNC works on the following principle: he has a database of all possible combinations, which can be formed from all the symbols. There are tens of thousands of them. Each combination has its own number. When you start the drums HCS throws out a random number, and the combination that corresponds to it - displayed on the field.
Hence the conclusion: strategies with a guaranteed effect does not exist. Play for fun if the slots give you a thrill, and bet as little as possible to stretch your deposit.
The slot is stylized like old slot machines. Its background is bright, but without interfering with the game special effects. The field is small, with a 5+ Cashpot payout table above it, and a block of HyperBet buttons below it. The rest of the slot controls are centered at the bottom. From left to right are the menu, Buy Bonus, bet selection, a large button for manual start, and smaller buttons for autospin and accelerated reel spins. There are no settings for autospin: you can only activate it, and then deactivate it manually. The balance is shown on the bottom left, the size of the selected bet on the right. In the center at the bottom is shown the amount just won. Before the start of the session we advise:
Play in demo mode, choosing different levels of HyperBet. This way you can practically understand how many symbols are involved in each, and how different the payouts and payoffs will be.
Lower the bet to the minimum. Note that when you switch HyperBet levels, the bet size changes too.
Speed up the reels and/or start autospin if you wish.

A mobile version has been created for iOS and Android. It's lighter, so it loads quickly and doesn't require a powerful gadget to play. The interface and design will automatically adjust to the screen size, even if it is non-standard. Buttons will be redistributed closer to the corners to make them comfortable to press. You can play the mobile version from your phone or tablet.
What impression the Casinoz team had of the slot: generally positive, but not enthusiastic. The Joker Spark 7s should appeal to fans of simple and uncomplicated slots, or those who like a retro look. It has no bonus features, so the very first (and cheapest) HyperBet level in the slot has nothing but simple spins with Wild.
