Introduction

123 BOOM!™ is a 5×4 1,024 Ways slot created by 4ThePlayer.com. Ways removes paylines, making it easier to see where the win is.

Explosive Wins

This is an Explosive Wins game – symbols form wins, explode, and are removed from the reels. All symbols removed from the reels are replaced by symbols from the beginning of the reels.

Only the highest win in view is paid. If multiple wins have the same payout, then the highest number of symbols, followed by the highest of a kind win in view, followed by the symbol with the best paytable payouts, is paid.

Slot Slider™ Spin Modes

This game can be played in two modes: Slide Spin or Top Spin.

A win is formed from consecutive symbols. In Slide Spin the reels spin right to left and pays left to right columns. In Top Spin the reels spin top to bottom and it pays bottom to top.

On PC the default play mode is Slide Spin; use the Change Spin button (small button with rotation symbol) to change to Top Spin. On mobile play Slide Spin in landscape view and Top Spin in portrait view.

Payouts and game features are unchanged in both modes.

How to Play

The player chooses their bet amount using the + and – symbols above or below the spin button. All wins are multiplied by the bet. For details on win payouts see the game paytable.

To play the game, the player presses the spin button – the largest button with 4 arrows. If playing on PC and if enabled from the game options menu, the space bar can be used to spin.

Press the ►► button after the spin has finished to see the results quicker.

Symbols

Cannon Bonus Scatter

3 or more Cannon Bonus Scatters in view will trigger the Bonus Feature.

Cannonball Wild

The Cannonball Wild substitutes for every symbol other than the Cannon Bonus Scatter.

Pirate

The Pirate is the top paying symbol.

Sliding Cannonball Wild Feature

If there are no wins in view on the reels and there are Cannonball Wilds that are not at the end of the reel, then the sliding Cannonball Wilds will slide in the direction of the spin.

As they slide, they will destroy symbols in front of them, removing them from the reels until they reach a position where they can create a win or they reach the end of the reel.

Bonus Feature

All triggering Cannon Bonus Scatters are collected, removed from the reels, and stored in the scatter collection area. Any additional, one or more, Cannon Bonus Scatters that appears during the Bonus Feature are also collected.

If there are no wins and all Cannonball Wilds that can slide have done so, then a Cannon Bonus Scatter that has been collected will be used to fire a WILD on to a random reel in the reel’s first position.

After every explosion, the win multiplier is increased before the win is paid, otherwise the multiplier remains as before the spin. The Bonus Feature multiplier starts at X2.

When all Cannon Bonus Scatters that have been collected have been used the Bonus Feature and spin ends.

How to Calculate a Win With 1,024 Ways

If any of the reels contain more than 1 instance of the symbols, the win will be multiplied. Multiply the number of symbols on each of the reels to get the final payout multiplier.

For example, if the first column contains 2 symbols, second column 3 symbols and third column 2 symbols, the paytable value is multiplied by 2*3*2=12.

Autoplay

Autoplay allows the player to play without pressing spin. To open autoplay, press the autoplay button – the small button with 4 arrows and a play icon in the middle.

The player has the option of choosing the number of spins, loss limit, and single win limit. The spins will automatically stop when the chosen number has completed or the loss limit or single win limit is hit.

When the autoplay is active, the spin button becomes a stop button which displays the number of spins remaining. To stop autoplay spins, press the stop button.

Please note that Autoplay is not available in the UK.

• Paytable – Displays the payouts for each symbol and description of the game features
• Space to Spin – Available on PC only, if enabled the player can press space to spin
