Gloop DoubleUp Slot Features

Double Up, Spill, Gloop Wilds, Gloop Jars, Goo Lab, The Blob and Double Trouble drive the action in Gloop DoubleUp, with each mechanic adding merging slimes, wild coverage, or bonus progression to the online slot gameplay.

Double Up

After every win, the winning slimes merge into the next tier and double, starting at x2 and building to x64. A merged King Slime becomes a Gloop Wild with double its multiplier. Multipliers on the same way add together, so a x2 slime and a x4 Wild pay x6. A merge can also splat onto the cells around it and turn them into the same new slime.

Spill

Spill tips a bucket of goo over two neighbouring reels and turns every covered cell into a Gloop Wild. The Spill Spins boost places a Spill on every spin, while Super Splat pushes the effect further with x2 Wild Spills and splatting merges.

Gloop Wilds

Gloop Wilds land on reels 2 to 6 with x2, x4 or x8. They substitute for every slime except Jars, and they clear once they join a win. When King Slimes merge, they create even bigger Wilds, which makes the merging system matter across the whole board.

Gloop Jars

Gloop Jars trigger bonuses when 3 or more land anywhere after tumbles stop. Three Jars usually lead to Goo Lab, while 5 or more always give The Blob or Double Trouble. During a bonus, landing 3 or more Jars adds 3 spins, so collections can extend the round.

Goo Lab

Goo Lab gives 12 free spins. Every merged slime sticks in place for the rest of the bonus while the reels spin and tumble around it. Those stuck slimes keep merging and doubling whenever they win again, and the two lowest slimes, Drip and Blob, are removed.

The Blob

The Blob gives 6 free spins. On every spin, the Blob drops as a 2 x 2 block of Gloop Wilds sharing one multiplier, starting at x1. Each time it wins after a spin, the multiplier doubles up to x8, and the block can grow to 2 x 3.

Double Trouble

Double Trouble gives 12 free spins. Every merge fills the Gloop-o-meter, and every 4 merges double the multiplier on all wins, up to x512. The multiplier never resets, and Drip and Blob are removed for this bonus, which keeps the focus on chaining merges.

Boosts & Features

Three boosts stay on until you switch them off and cost their price on every spin, while three features start the bonus straight away for a single cost. This menu lets you push the Gloop DoubleUp Addictive Gaming slot into different online slot gameplay styles, from stronger Jar collection to direct bonus access and heavier Spill setups.

• Jar Boost: x1.2 the bet per spin; more Jars land, so bonuses trigger more often.
• Spill Spins: x5 the bet per spin; a Spill happens on every spin.
• Super Splat: x25 the bet per spin; a Spill of x2 Gloop Wilds on every spin, and every merge splats 2 to 4 cells and lands at x4 instead of x2.
• Goo Lab: x100 the bet; starts 12 free spins immediately.
• The Blob: x200 the bet; starts 6 free spins immediately.
• Double Trouble: x300 the bet; starts 12 free spins immediately.

Gloop DoubleUp Slot Review

Gloop DoubleUp builds its identity around a slime laboratory, where teal goo, metal machinery and cartoon monsters create a loud, playful frame for the action. The merging symbols and Wild effects are not just decoration here, because the visual setup directly supports the doubling theme and makes the board easy to read.

The best part of Gloop DoubleUp is how the Double Up chain, Spill effects and bonus selection all feed into one another. High volatility suits the design, because smaller wins can vanish quickly while the merge ladder and 100,000x ceiling keep the upside meaningful. The buy menu adds control, but it also increases the cost of experimenting.

Gloop DoubleUp combines multipliers, Jar based triggers and distinct feature modes, with the same theoretical RTP across the base game, boosts and bonus buys. That structure gives it real depth, and the 96.05% RTP supports the overall package. High risk and feature depth define the verdict.
