Firebolt Multi 7s Hold and Win

Firebolt Multi 7s Hold and Win Overview

Firebolt Multi 7s Hold and Win is a retro sevens-and-bars slot from Kalamba Games, released on 6 June 2024. It plays on 5 reels and 3 rows with 10 fixed paylines, and its features are switched on step by step through a four-level HyperBet panel: multiplier wilds, multiplier sevens, a Hold and Win bonus and four cashpots.

Kalamba rates the volatility 10 out of 10 and lists a maximum coinciding win of 45,000x the bet, with a hit frequency of 23.91%. SlotCatalog gives an RTP of 95%, high variance and a 10,000x maximum, with bets from $0.05 to $100. The numbers below come from our own demo session, played at €10, €30 and €100.

A Fruit Machine on Fire

The reels sit in a red cabinet framed by neon strips, with flames licking at the base of the machine. The symbols are the classics: sevens in orange, silver, red, blue and green, single and double BARs in neon colours, and sparkling diamonds that carry cash values. Four jackpot plaques – MINI, MINOR, MAJOR and MAXI – hang above the reels, and a row of four icons below them shows which features the current HyperBet level has unlocked.

The Paytable

The line pays are printed in euros for the current bet. At €10, five orange sevens pay €1,000 – 100x the bet – with €200 for four and €50 for three. Silver sevens pay €400, €100 and €40, red sevens €200, €40 and €30, blue sevens €100, €30 and €20, and green sevens €50, €25 and €12.

A mixed line of any sevens pays €10 for five, €5 for four and €2 for three, so the colour of the sevens matters far more than their number. The payline page shows all ten lines: the three rows plus seven V-shaped and zig-zag lines, all paying left to right from the leftmost reel.

HyperBet: Four Levels of Features

Kalamba’s description of the game spells out what each HyperBet level adds:

Level 1 is the plain base game, paying only for standard symbol combinations. Level 2 adds multiplier wilds, plus BAR and seven symbols that can carry a 2x or 3x multiplier. Level 3 makes the Hold and Win symbols active, so six or more of them trigger the bonus. Level 4 adds Super Hold and Win symbols: any combination of three or more Hold and Win and Super Hold and Win symbols pays the total of the values on them.

In our captures at Level 4 the panel read BET LEVEL 4 with a total bet of €30, and all four feature icons were lit.

Multiplier Wilds and Sevens

The multiplier features were easy to spot. In one spin a stack of x2 WILD symbols filled the fourth reel next to a diamond worth 18.00, and the spin paid €12.00. In another, green sevens on the second reel carried x3 badges, the Level 2 multiplier sevens at work. A later spin paid €36.00 on the €30 bet.

The Hold and Win Bonus

Six or more diamonds on the reels start the Hold and Win bonus when HyperBet Level 3 or 4 is active. The diamonds lock in place with their cash values, and the rest of the grid respins to land more. Kalamba says that covering the grid earns a special prize and a chance at one of the four cashpots.

Our bonus round at the €100 bet ended with the grid almost full. The diamonds showed values from 8.00 up to 480.00 – among them 70, 60, 100, 90, 80 and two 180s – and a large collector diamond below the reels added 1,000.00. The round paid €1,448 in total, 14.5x the bet.

Cashpots and the 45,000x Ceiling

The cashpot plaques change with the bet settings. At the €30 Level 4 bet they read MINI 600, MINOR 1,500, MAJOR 30,000 and MAXI 600,000 – 20x, 50x, 1,000x and 20,000x the stake. At the €100 bet the same plaques showed 200, 500, 10,000 and 200,000, so the plaque values appear to follow the HyperBet configuration rather than the total bet alone.

Kalamba’s own figure for the game is a maximum coinciding win of 45,000x; the sister game Firebolt Max 7s Hold and Win is listed at 27,000x. SlotCatalog’s 10,000x is a more conservative figure.

Our Session in Numbers

The balance tells the story of a high-volatility game. We started the captures at about €10,739, and the small base-game wins did not keep up with the €30 and €100 stakes: the balance slid to €10,619, then €10,555 and €10,360 before the Hold and Win round. The bonus pushed it back up, and by the time we opened the paytable at the end of the session it stood at €11,777.

That pattern – a steady drip of small line wins, then one feature that decides the session – is exactly what a 10/10 volatility rating promises. It also explains why the MAXI plaque is so far above everything else on the screen: the top prize is designed to be rare.

Buy Bonus

A Buy Bonus button sits at the bottom left. Kalamba lists two buy options, both of which start the Hold and Win bonus straight away. We did not open the buy menu in our captures, so we cannot quote the prices.

Who Should Play It

Firebolt Multi 7s suits players who like classic fruit-machine symbols but want modern features on top. The HyperBet panel is the key decision: at Level 1 it is a simple ten-line sevens slot, while Level 4 turns on every multiplier, the Hold and Win bonus and the full cashpot ladder. With a volatility rating of 10/10, long quiet stretches are part of the design.

If you enjoy this style, Kalamba’s Multi Blitz 7s and Firebolt Max 7s play in the same family of sevens.
