Game Overview

Gigantoonz is an 8-reel, 8-row cascading video slot developed by Play’n GO. The game features cluster wins and unique bonus mechanics, offering a dynamic grid experience. Bets can be placed from a minimum of £0.20 up to a maximum of £5.00 per round.

How to Play Gigantoonz

1. Select your desired bet using the plus or minus buttons at the bottom of the game screen, or by clicking one of the available bet buttons.
2. To start a round, press the START button or use the spacebar on your keyboard.
3. Symbols that appear on the grid determine any prizes, according to the paytable.

Game Rounds and Cluster Wins

Wins are achieved by forming clusters of 6 or more adjacent matching symbols, connected either horizontally or vertically without any gaps. Winning combinations can begin from any point on the grid. When a cluster is formed, those symbols are removed, and new symbols drop to fill the spaces, potentially creating more wins through cascading. These cascades continue until no new winning clusters appear. All winnings from multiple clusters in a single round are combined, and any Feature, Bonus Game, or Scatter payouts (where applicable) are also added to the total cluster win. Only the highest win is paid per winning symbol combination. All wins are credited at the end of the round.

The game round is played with the bet amount that was active when it began. The bet cannot be adjusted during an active round. The paytable can be accessed and toggled for information on symbol payouts.

Mega Symbols and Wilds

• Mega symbols may appear in different sizes, including 2×2, 3×3, 4×4, 5×5, 6×6, or 7×7 blocks. Each has a random cluster value of up to 13 and counts as a single symbol for determining cluster wins.
• The cluster value of a mega symbol impacts the payout received for that win. When a mega symbol is part of a win, it leaves behind a WILD symbol in its position on the grid.
• If a mega symbol cannot drop further during cascades, it fills the remaining area with regular 1×1 symbols that do not hold a cluster value.
• If a round does not produce a win, between 5 and 10 QUANTUM WILDS may be randomly added to the grid. GARGANTOON WILDS can also appear through the QUANTUMETER feature. All WILDS substitute for any symbol to help form winning clusters.

Quantumeter and Bonus Features

Every winning symbol contributes one charge to the QUANTUMETER, while mega symbols contribute their cluster value instead. The QUANTUMETER tracks up to 100 charges and has four feature levels:

• 25 charges: DISINTEGRATION – removes all instances of four randomly chosen symbols from the grid.
• 50 charges: METAMORPHOSIS – randomly transforms all instances of a selected symbol into another, including any mega symbols.
• 75 charges: RADIATION – introduces up to four mega symbols and two to five QUANTUM WILDS to the grid at random.
• 100 charges: GARGANTOONZ! – activates in two stages once no further cascades can occur:
  • First, all mega symbols on the grid are converted into mega GARGANTOONZ (with at least three guaranteed), plus two to four 1×1 GARGANTOONZ are added. Mega GARGANTOONZ remain on the grid, even after winning combinations are made.
  • Next, the mega GARGANTOONZ break apart into 1×1 GARGANTOONZ, which are then removed through standard cluster wins.

The QUANTUMETER triggers the next charge feature available at the end of cascades. Once all features have been played, the QUANTUMETER becomes inactive until recharged.

Controls and Actions

• Changing Your Bet: Increase or decrease your wager by clicking the appropriate bet button, or using the plus and minus controls.

• Start / Spacebar: Initiate the round using the start button or by pressing the spacebar.

Unfinished Games and Malfunctions

If a game round is interrupted, all progress and bets are saved until you resume play. You can continue any unfinished round from the point where it was left. Bets that remain unresolved for 90 days in incomplete games will be declared void. In the event of any malfunction, all pays and plays are invalidated.
