King Kong Even Bigger Balls

King Kong Even Bigger Balls is an online video slot developed by Blueprint Gaming. It builds on the ongoing King Kong Cash series and adds a progression system alongside feature staking, which, paired with the football theme, separates it from earlier entries in the lineup.

Gameplay features and bonuses

King Kong Even Bigger Balls uses a 6×4 grid with 4,096 ways to win and a top payout that can reach 10,000x the stake. The game sits in the high volatility category and runs on an RTP rate of 93%, which places it on the lower end of the spectrum.

Wild Symbol: Wilds can appear on every reel except the first one. They substitute for all regular symbols but do not replace Kong Collect, Bonus, Scoring Wheel, or Cash Prize symbols.

Cash Prize Symbols: There are 2 types of Cash Prize symbols. These display fixed monetary values that can be collected through several features.

Kong Collect Symbol: At the start of the game, the Kong Collect symbol is active on reels 1 and 6. When it appears in view together with 1 or more Cash Prize symbols, the Kong Collect feature activates. The symbol expands to cover reel 1, reel 6, or both and collects the values shown on all visible Cash Prize symbols. Every Kong Collect that lands also advances the Unlock Trail, which gradually introduces additional mechanics and figures.

Unlock Trail Progression: The Unlock Trail introduces new symbols and mechanics in stages, with each milestone permanently activating an upgrade. All unlocked features remain active for the rest of the session and apply to the base game and all bonus modes.

• Unlock 2 – Win Streak Kong Collect: Cash Prize symbols stay locked in position during Respins, and any newly landed Cash Prizes also remain in place until a Respin produces no additional such symbols.
• Unlock 5 – Win Stepper Kong Collect: The Cash Prize symbols that trigger the feature move upward or downward and fill the entire reel with Cash Prize symbols.
• Unlock 8 – Win Blast Kong Collect: The triggering Cash Prize symbols are collected before the reels clear, after which new symbols cascade into view. Any newly landed Cash Prize symbols are also collected, with this sequence repeating up to 4x.
• Unlock 12: Introduces the Scoring Wheel symbol.
• Unlock 16: Activates the Goal Blitz feature.
• Unlock 20: Activates the Even Bigger Balls Bonus.

Bonus Symbol: 3 or more Bonus symbols that land at the same time trigger the Kong Bonus Spins feature or the Even Bigger Balls Bonus if it has already been unlocked. The number of Bonus symbols determines both the number of awarded spins and an instant cash prize, which scales upward with additional symbols.

Kong Bonus Spins: During this mode, every spin that lands a Kong Collect symbol awards the value of all visible Cash Prize symbols. Collecting Kong Collect symbols also grants extra spins and applies multipliers to Cash Prize values. 3, 6, 9, or 12 collected figures award 5 extra spins and increasing multipliers that range from 2x up to 10x. The bonus ends once all spins are used, and the total winnings are paid.

Goal Blitz Feature: Cash Prize and Scoring Wheel symbols that land without a Kong Collect present are added to the Goal Blitz pot. On a spin that produces no wins, the pot may animate and trigger the feature. The player selects a random modifier that immediately alters the next outcome:

• Bonus Boost: Adds extra Bonus symbols and guarantees at least 3.
• Win Spin: Adds high-paying symbols, including Wilds, and guarantees a win.
• Ball Rush: Converts a random reel into Cash Prizes or Scoring Wheels and guarantees at least 1 Kong Collect on reel 1, reel 6, or both.
• Super Collect: Gathers all visible Cash Prize values at once. Scoring Wheel symbols resolve first.
• Kong Strike: Adds a Kong Collect symbol to reel 1, reel 6, or both and guarantees a collect win.

Even Bigger Balls Bonus: Once unlocked, 3 or more Bonus symbols award 10 spins. Before the bonus begins, the player may select up to 5 mystery picks to reveal upgrades:

• Cash Boost: Increases the lowest visible Cash Prize by 1x to 5x, increasing with each reveal.
• +Spins: Awards up to 5 additional spins.
• Cash Attack: Limits reels to Cash Prize, Scoring Wheel, and Kong Collect symbols.
• +Balls: Adds extra Cash Prize symbols.
• Trail Boost: Increases Unlock Trail multipliers up to 15x.
• +Collect: Adds additional active Kong Collects.
• +Wheel: Adds extra Scoring Wheel symbols.

Note: All upgrades except Cash Boost can be revealed only once. The bonus may begin immediately without upgrades if the start option is revealed first. The round ends after all spins are used, and the total accumulated winnings are paid.

Design and Soundtrack

King Kong Even Bigger Balls presents a playful jungle football setting built around bright greens, sandy tones, and a sunlit pitch framed by palm trees. The grid sits inside a stone-and-bamboo frame, filled with cartoon animal characters, bold 10–A card symbols, and football-themed figures. Animations stay smooth and lively, though the screen can feel busy early on. The soundtrack follows a light, upbeat rhythm that supports the theme.

Fans of progression-focused slots may want to try Pan’s Arcadia by Thunderkick. Football-themed gameplay also appears in Spin & Score Megaways by Pragmatic Play, which puts a stronger emphasis on the sports angle.

The Bottom Line

King Kong Even Bigger Balls fits into Blueprint’s portfolio as a feature-heavy slot built around gradual progression. The Unlock Trail introduces mechanics at a measured pace and provides continuity across sessions, though the strong emphasis on collection systems results in slower action. The jungle football setting, themed symbols, and animations adjust the presentation, but the core structure remains largely untouched and closely aligned with earlier King Kong Cash titles. This release is best suited to players who favor extended progression and methodical gameplay over fast sessions.
