Boomerang games: eight slots and what we actually know about them
Most casino game guides list every title they can find and copy a return figure next to each one. This page works the other way round. We picked eight slots from the material the Boomerang brand publishes, checked what the studios themselves confirm, and wrote down exactly that. Where a number is not confirmed by a primary source, we say so and show you where to find it in the game. Each title also gets the angle this site cares about most: how the game behaves when a bonus with wagering is running on your balance.

Slot types you will meet in a casino lobby
Online slots fall into a handful of families. Line slots pay when matching symbols land along fixed paylines, read from left to right. Ways slots drop the lines and pay for matching symbols on adjacent reels in any row. Cluster slots, such as Snoop Dogg Dollars, use a large grid and pay when enough identical symbols touch each other. Hold-and-win or coin-collection games, a label several titles here carry in their names, usually lock special symbols in place for a series of respins. The family tells you how a game is built; it does not tell you the return, the volatility or the size of the top prize, which differ from title to title.
Slots are only one part of a typical lobby. Table games such as roulette and blackjack are covered on our table games page, streamed dealer tables on the live casino page, and a deeper look at reel mechanics on the slots page. If you are interested in sports markets, see the betting guide.
The studios in this guide
Three developers are confirmed for five of our eight titles. BGaming made Snoop Dogg Dollars and Elvis Frog TRUEWAYS. Endorphina made Burning Coins 20 and Prestige Crown. Play'n GO made Rise of Olympus Extreme. Big names such as Pragmatic Play, Evolution, NetEnt or Hacksaw Gaming are not part of this guide; that says nothing about whether their games appear in the lobby, only that we have not reviewed them here. The operator's provider filter shows which studios are actually live for your account.
RTP and volatility: read them in the game, not in a list
Return to player is a long-run theoretical average: the share of all money staked on a game that it pays back over a very large number of spins. Volatility describes how that return is distributed — frequent small wins or rare large ones. Both are set by the game's maths model, and many studios publish the same title in several RTP configurations so that operators can choose. That is why a figure you find on a review site can be correct and still not apply to the copy you are playing. Open the info panel (usually an "i" icon or a menu entry) and look for the return percentage there. If several figures are listed, they typically belong to different modes, such as a feature purchase.
How games count toward wagering
When you play with a bonus, two rules decide which game you should open. The first is the contribution rate: slots commonly count 100% of each stake toward the wagering requirement, while table and live games often count far less or nothing. The second is the maximum bet allowed while wagering is active. Illustrative example, not Boomerang's terms: a 50-unit bonus with 30× wagering means 1,500 units of stakes. On a slot counting 100%, that is 300 spins at 5 units. On a game counting 10%, the same requirement would need 15,000 units of stakes — in practice, not achievable. Our wagering guide walks through these sums step by step.
Demo first, money second
A demo loads the real game with play credits. It is the cheapest way to see how often features trigger and how quickly a balance moves at the stake you have in mind. Demo results promise nothing about real play, but they help you judge whether a game's rhythm suits your budget. Before playing for money, set deposit and session limits — our responsible gambling page lists the tools to look for.
