Huff N’ Puff CollectR - Demo & Slot Review

Huff N’ Puff CollectR runs on a 6×6 grid that can expand up to 8×8, and it does not use paylines in the usual sense. Instead, the game uses ELK’s CollectR mechanic, where four collecting pig symbols move around the grid and gather symbols to create payouts. The top RTP is 96%, lower configurations also exist, volatility is high, the hit frequency is 26%, the bet range is 0.20 to 100, and the maximum win is 5,000x stake.

The feature set is dense, with collection and feature symbols, a collection meter, a Golden Wheel, Hat Mania, Mega Hat Mania, Big Tony’s extra chance, wolf demolition, corner bombs, bonus games, super bonus games, piggy coins, and feature buys.

• CollectR: Huff N’ Puff CollectR starts on a 6×6 grid and can expand to 8×8. The four pigs move around the board and collect adjacent gems of their own color plus any feature symbols they can reach. Collected symbols disappear, new ones drop in, and the sequence continues as long as at least one pig can still collect something. If two pigs block each other, they can trigger a Switcheroo and swap places or relocate. If three pigs line up horizontally or vertically, they fight, clear a 5×5 area, then launch across the grid and remove more symbols while also being able to trigger bombs, construction, scatters, or super scatters. Gems removed during this pig fight sequence do not count toward the collection meter.
• Gems: The regular symbols are blue, green, purple, and red gems, each tied to one pig. Gems can be upgraded through the game up to level 7. At the top level, gems are worth 1.5x to 5x bet each, depending on color.
• Collection Meter: The Collection Meter tracks gems and wilds collected by pigs, except during Wolf Construction. When the meter fills, it releases one pending feature symbol. Up to three feature symbols can be queued, and if several are pending they are released together. When a feature symbol is released, a number of gems on the board are converted into that feature symbol.
• Feature symbols: The game uses nine feature symbols: Scatter, Super Scatter, Hat, Upgrade, Upgrade All, Wolf Construction, Transform, Jackhammer, and Wild.
  • Upgrade raises gems of the collecting pig’s color by 1 to 3 levels, up to level 7.
  • Upgrade All raises all four gem colors by 1 to 3 levels, up to level 7.
  • Transform changes a cluster next to the pig into that pig’s color and can also turn gems into feature symbols.
  • Jackhammer places pig tokens into empty spaces so pigs can cross those spaces once to reach more symbols.
  • Wild substitutes for any gem at its current level, though pigs cannot finish their movement on a wild.
• Wolf Construction: Wolf Construction starts a separate collection sequence where the wolf moves column by column across the grid. He can collect symbols, but not Jackhammer or Transform symbols. He can also trigger corner bombs. If the wolf reaches a pig, they fight. If the wolf wins, the crane multiplier increases by +1 and that pig is removed. If the pig wins, Wolf Construction ends and the crane multiplier is applied to the total value already collected. If the wolf defeats all four pigs, he collects all remaining symbols on the grid before the crane multiplier is applied.
• Golden Wheel: When the pigs or the wolf collect all available collectable symbols on the board, the Golden Wheel triggers. It can award Hat Mania, Mega Hat Mania, the Bonus Game, the Super Bonus, or an instant cash payout.
• Hat Mania: Hat Mania awards 3 drops on a 6×6 grid. Only hats and blank spaces appear. Landing 3 or more hats on one drop gives +1 extra drop. Hats create or upgrade frames in this order: straw, wood, brick. If a hat lands on a brick frame, it places another brick frame elsewhere. At the end of the feature, all visible frames reveal coin values based on their level, ranging from 0.25x to 2,500x bet.
• Mega Hat Mania: Mega Hat Mania uses the same rules as Hat Mania, but it is played on an 8×8 grid. Hats can be as large as 8×8, and the feature starts with a number of mega hat drops before the normal drops begin.
• Wolf Demolition: Wolf Demolition can trigger when the pigs cannot collect anything else. It removes all symbols and 1 to 3 pigs, then drops them back onto the board in a new order. This acts as a reset and board reshuffle feature.
• Corner Bombs: Each corner of the starting 6×6 grid contains a bomb, and each bomb has a color linked to one pig. If a pig collects a symbol sitting on a bomb of the same color, that bomb detonates once pigs can no longer move. The explosion clears a 3×3 area, removes all pigs and gems inside it, and also removes the connected pipe section around the board. Removing pipe sections can expand the board up to 8×8. Those pipe openings become tunnels, and pigs can move through them if there are collectable symbols at both the entry and exit. Tunnel sections can reveal up to two feature symbols. A well appears in a corner once at least two pipe sections have been removed, and pigs can move between wells if collectable symbols cover two or more wells.
• Big Tony’s Extra Chance: Big Tony’s Extra Chance can trigger when the pigs are stuck. It activates 1 to 4 corner bombs instantly, and the pigs leave the grid before the explosions resolve. This can reopen the board, remove symbols, expand the play area, and create new routes into other features.
• Bonus Game: Landing 3 Scatters triggers the Bonus Game and awards 5 free spins. During the bonus, Hat symbols create or upgrade frames, and at the end of each round the frames are filled with coin values. Frames persist between free spins. Landing 3 or more hats in one spin gives +1 free spin. If Scatter is collected during any bonus round, it triggers the Saw Feature, which creates or upgrades frames on every position the symbol passes over. Both Collection Meter progress and gem levels stay persistent during the bonus.
• Super Bonus: If one of the three triggering scatters is a Super Scatter, the game awards the Super Bonus instead of the normal bonus. It uses the same persistent rules as the regular bonus, but it starts with the Saw Feature already active before the first free spin.
• Piggy Coins: Piggy Coins can land on any base spin or free spin. They are added to the Piggy Bank. When added, they can trigger either the Jackpot Wheel or the Super Wheel. The Jackpot Wheel awards 10x to 2,500x bet. The Super Wheel can award Mega Hat Mania, Hat Mania, the Bonus Game, the Super Bonus, or an instant payout.

  • Bonus Hunt costs 3x bet, making the bonus 3 times more likely to trigger.

  • Mega Hat Mania costs 50x bet.
