GM Casino | Electronic Games Guide – Slots, Fishing & RTP Tips

Reels: The vertical columns that spin on a slot machine, usually 3, 5, or more. Each spin stops on a random combination of symbols.

Paylines: The winning paths across the reels, usually from left to right or in special patterns. Classic games often have 5–25 paylines, while modern titles can offer 243 ways or more (all-ways mechanics).

Symbols: The various icons that appear in the game, usually divided into:

• High-value symbols: Premium icons with the highest payouts (characters, gems, etc.)
• Low-value symbols: Basic symbols (A, K, Q, J, 10, etc.)
• Wild symbols: Substitute symbols that can replace others to form winning combinations
• Scatter symbols: Special symbols that usually trigger features when 2–3 or more land anywhere
• Bonus symbols: Keys to launching special bonus games

RTP (Return to Player): The theoretical percentage of total wagers returned to players over the long term. For example, a game with 96% RTP should, in theory, pay back 9,600 out of 10,000 wagered. For more details, see the slot strategy guide.

Volatility: The risk level of a game. High-volatility slots pay larger prizes but less frequently, while low-volatility games pay smaller amounts but hit more often.

Free Spins

Trigger conditions: Usually triggered by landing 3 or more Scatter symbols

Number of spins: Typically 5–25 free spins, sometimes with the ability to retrigger

Common enhancements:

• Win multipliers: All wins can be boosted from 2x up to 50x
• Extra Wilds: Additional Wild symbols to increase hit rates
• Sticky Wilds: Wild symbols stay locked in place for multiple spins
• Feature selection: Players may choose between high-risk/high-reward or low-risk/more-spin options

Why this matters: Free spins are often the most profitable part of a slot, accounting for 60–80% of total returns. When choosing games, prioritise slots with strong and interesting free spin features.

Bonus Games

How to enter: Typically by landing 3 or more Bonus symbols or hitting special symbol combinations

Common types:

• Pick-me games: Choose chests or cards to reveal prizes and multipliers
• Wheel games: Spin a wheel to determine your prize
• Battle-style games: Fight enemies and earn rewards when you win
• Board-style games: Roll dice to move along a path, collecting prizes on the way

Strategy tip: Bonus games almost always pay something, often at least 10–20x your bet. Be patient while waiting for them to trigger, and once inside focus on maximising your return.

Feature Buy (Bonus Buy)

How it works: Players can pay a fixed cost (usually 50–100x the current bet) to skip the base game and jump straight into the free spins or bonus rounds.

Advantages:

• Saves time by not waiting for features to trigger naturally
• Guarantees access to the most exciting part of the game
• Appeals to players who want to experience big-win potential quickly

Disadvantages:

• High cost with no guarantee of breaking even
• Extremely high volatility; a few unlucky buys can quickly drain your bankroll

Recommendation: Only use feature buys when your budget comfortably allows it and you fully understand the game’s mechanics. Beginners should avoid this option and first get used to the natural game flow.

Tip 1: Target Selection Strategy

Conservative style (recommended for beginners): Focus on small and medium fish to maintain stable returns.

• Target fish in the 2–10x range
• Use low-multiplier cannons (0.1–1x)
• Prioritise fish near the edges of the screen that are about to leave
• Avoid wasting shots on very tanky targets

Expected outcome: While individual payouts are small, the hit rate is high, which helps extend your playtime and control losses. This is ideal for beginners or players with smaller budgets.

Aggressive style (for experienced players): Hunt big fish and bosses to chase large payouts.

• Use high-multiplier cannons (10–100x)
• Focus fire on targets worth 50x or more
• Observe boss spawn patterns and time your attacks
• Coordinate with other players to concentrate fire when necessary

Risk warning: Volatility is extremely high—you may lose your bankroll quickly. However, successfully killing a boss can result in wins of several thousand to tens of thousands of units in a single hit.

Tip 2: Adjusting Cannon Multipliers

Dynamic adjustment principles:

• Small fish ⇒ small cannon: Use 0.1–0.5x shots for 1–5x fish to avoid waste.
• Medium fish ⇒ medium cannon: Use 1–5x shots for 10–20x fish.
• Big fish ⇒ big cannon: Use 10–50x shots for 50x+ fish to ensure you can kill them efficiently.

Common mistake: Using 100x shots on a 2x fish only yields a 200 payout even if you hit, which is very inefficient. Firing 0.1x shots at a 100x boss might take 50 shots or more, often resulting in a net loss.

Tip 3: Aiming and Leading Your Shots

Movement prediction: Fish are constantly moving and your shots have travel time. You need to aim where the fish will be, not where it is now.

Fast fish: Aim 1–2 body lengths ahead of the target.

Slow fish: Aim directly at the body.

Straight-line movement: Easy to predict and yields a high hit rate.

Irregular movement: Hard to predict; skip these targets unless their multipliers are especially high.

Practice tip: Use the lowest cannon multiplier while practising your aim. Once your hit rate stabilises above 70%, gradually increase your stake.

Tip 4: Using Special Weapons Effectively

Many fishing games offer special weapons or skills. Using them correctly can significantly increase your efficiency:

• Torpedoes/missiles: Area-of-effect attacks suitable when many fish are clustered together
• Electric shock: Screen-wide attack that damages all fish
• Freeze: Slows fish movement, improving your hit rate
• Lock-on: Auto-aim that tracks a target to ensure hits

Best times to use them:

• Use high-damage weapons when a boss appears
• Use area attacks when multiple big fish appear at once
• Consider purchasing special weapons only when your balance is healthy

Small Budget (100–500 units)

Recommended game types:

• Low-volatility slots: Smaller but more frequent wins that extend your playtime.
• Classic 3-reel slots: Low bet sizes, sometimes starting from as little as 0.1 units.
• Arcade-style games: Each round has a predictable cost with quick in-and-out sessions.

Avoid: High-volatility Megaways slots, progressive jackpots, and high-multiplier fishing games.

Strategy: Stick to minimum bets and focus on entertainment time rather than chasing big wins. Combine with the first deposit bonus to effectively double your initial bankroll.

Medium Budget (500–2,000 units)

Recommended game types:

• Medium-volatility 5-reel slots: A good balance between fun and winning potential.
• Fishing games (conservative style): Focus on small and medium fish while controlling cannon multipliers.
• Electronic poker: High RTP and relatively slow bankroll drain.

Worth trying: Occasional small feature buys to experience the highlight bonus rounds.

Strategy: Allocate about 20% of your bankroll to high-volatility games for big-win potential, and the remaining 80% to more stable games to extend your playtime.

High Budget (2,000 units and above)

Recommended game types:

• High-volatility Megaways games: For players chasing win potential in the thousands of times their bet.
• Progressive jackpot slots: With a chance to hit life-changing prizes.
• Fishing games (aggressive style): Use high-multiplier cannons to target bosses for huge wins.
• Feature buy options: Directly purchase entry into bonus rounds.

Strategy: Be prepared to tolerate high volatility in exchange for the chance at life-changing wins. Still, always set strict stop-loss limits and avoid losing more than 50% of your planned daily budget.

Strategy 1: Choose High-RTP Games

RTP (Return to Player) indicates long-term expected returns. Choosing games with 96% or higher RTP helps slow down your loss rate.

High-RTP suggestions:

• Blood Suckers – 98%
• Mega Joker – 99%
• 1429 Uncharted Seas – 98.6%
• Electronic poker (with optimal strategy) – 99%+

You can usually see RTP values in the game info screen; always prioritise high-RTP titles.

Strategy 2: Make the Most of Free Spins and Promotions

GM Casino frequently offers free spin promotions, which are a zero-cost way to experience games and potentially win real money.

How to use them wisely:

• Use free spins on high-volatility games (since they are risk-free, they’re ideal for chasing big wins).
• Always check the wagering requirements to ensure bonus winnings can actually be withdrawn.
• Check promotions regularly so you do not miss valuable offers.

Strategy 3: Manage Your Time

Set a daily time limit for gaming (for example, 1–2 hours) to avoid excessive play.

Healthy gaming habits:

• Take a 5–10 minute break every 30 minutes of play.
• Don’t play when you’re tired or in a bad mood.
• Never extend your sessions just to “win back losses”.
• Keep gaming in balance with work, relationships, and other parts of life.
