How to Play Bloom Boom: Flower Clusters and Growing Multipliers
Bloom Boom is a 7×7 cluster slot where winning positions remain important after the flowers disappear. Make a group of at least five matching blooms, clear it and watch fresh symbols tumble into place. Each winning cell plants a multiplier spot that can double when a later win uses the same position.
This guide covers the shipped Bloom Boom rules: flower clusters, garden tumbles, multiplier spots from 2x to 1024x, the sun-charms feature and the published 96.5% theoretical RTP.
How Bloom Boom cluster wins form
Bloom Boom does not use fixed paylines. It searches the full 7×7 garden for matching symbols connected horizontally or vertically. Diagonal-only contact does not join two flowers into the same cluster. Five matching flowers is the minimum paying group.
- Choose a stake and spin. One wager resolves the complete tumble sequence.
- Find a flower cluster. At least five matching blooms must connect along their sides.
- Clear the paying flowers. The symbols pop out of the garden and their cells receive multiplier spots.
- Refill the spaces. New symbols fall into the empty positions.
- Check for another cluster. A new win continues the same sequence and can hit planted cells again.
- Settle the spin. The round finishes when no additional paying cluster remains.
How the multiplier garden grows
Every cell used by a winning cluster plants a 2x spot. If a later paying cluster uses that same position while the spot is active, its value doubles: 2x becomes 4x, then 8x, 16x and onward, up to 1024x. The values stay attached to board positions rather than to particular flower symbols.
A high-value spot only matters when a paying cluster lands on its cell. An empty patch of large multipliers is potential, not a payout. The board makes those values visible so you can follow how a tumble chain developed without treating the next refill as predictable.
A planted multiplier records what happened on that cell. It does not pull the next matching flower toward it.
Sun charms and 10 free spins
Landing three sun charms awards 10 free spins. The feature keeps the multiplier spots active between its spins, which lets repeat hits continue developing the same garden rather than starting from a blank multiplier layer every time.
That persistence is the central feature mechanic. Early feature clusters can plant useful positions, while later clusters may double them. The sequence can also pass without revisiting the strongest cells. Free spins create more opportunities inside one awarded feature, not a guaranteed profit or a minimum win beyond the rules shown in the game.
Bloom Boom RTP and volatility
Bloom Boom publishes a 96.5% theoretical RTP, equivalent to a 3.5% mathematical house edge over the long run. RTP includes base play and the free-spin feature in the complete model. It is not added separately to each part and does not predict the result of a bonus.
Persistent spots can concentrate value in tumble chains and feature sequences, so short-term outcomes can vary widely around the average. Compare the number with other games on the live Edge page, and read how RTP differs from house edge before using either figure as a session expectation.
Fairness and responsible play
The complete board sequence is resolved by the game service. The client presents the flowers, tumbles and spot growth; it does not change a result because of animation timing. Havoc Win’s provably fair guide explains how a committed round can be checked afterward.
Learn the multiplier layer in Fun play when available. Keep a fixed stake until you can explain why each spot changed, and decide a session limit before balance play. A nearly developed garden can make another spin feel tempting, but visible multipliers do not make the next cluster due.
Frequently asked questions
How do wins work in Bloom Boom?
A win needs at least five matching flowers connected horizontally or vertically on the 7×7 grid. Paying flowers pop, replacements tumble into their cells and another cluster can continue the same spin.
How do Bloom Boom multiplier spots grow?
Every winning cell plants a 2x multiplier spot. If a later win in the active sequence lands on that position, the spot doubles again, up to 1024x. The visible spot applies to wins using that cell under the game rules.
How do Bloom Boom free spins start?
Three sun charms award 10 free spins. Multiplier spots remain active throughout the feature, so repeat hits can continue developing the same garden of cell values.
What is the RTP of Bloom Boom?
Bloom Boom publishes a 96.5% theoretical RTP. It is a long-run average for the game model, not a guarantee that one spin, bonus or session will return that percentage.
