Brookstone Gems: how it plays
Brookstone Gems is a 7 by 7 cascade grid. Groups of 5 or more matching pieces that touch side by side form a cluster and pay. Paying clusters pop, the pieces above tumble down, new ones drop in from the top, and every cascade in the same spin lifts the multiplier (×1, ×2, ×3, ×5, ×8). It is a calm game: small clusters turn up often and the returns are gentle. You play with Pebbles, which have no value and cannot be bought or exchanged.
Play Brookstone GemsPlaying a round
- Choose your stake with − and +. One stake covers the whole spin, cascades included.
- Press Spin. A fresh grid of 7 × 7 pieces drops in; Quick makes the animations shorter.
- Any 5 or more matching pieces joined up, down, left or right form a cluster. The Diamond wild joins any cluster next to it.
- Each cluster pays the stake times the amount in the table for its size. Then it pops and the grid refills from the top.
- If the refill makes new clusters, they pay with the next multiplier: ×1, ×2, ×3, ×5, ×8. It stays at ×8 for any further cascades.

Good to know
- Pieces must touch along a side; corners do not join a cluster. Wilds on their own do not form a cluster.
- Every cluster on the grid pays at the same time, and clusters of different pieces add up.
- The multiplier goes back to ×1 at the start of every spin.
- A spin can return at most 5,000 times the stake; anything above that is not added.
- The stake is taken once per spin and everything the cascades return is added at the end.
- Results come from the random generator in your browser. Earlier spins have no effect on the next one.
- Every result is decided by your browser's cryptographic random number generator at the moment you play. Your account, level and earlier rounds make no difference.
- Without an account the game runs in demo mode with practice credits that are not saved. Signed-in players use their Pebbles.
- Pebbles have no cash value and cannot be bought or exchanged. If you run out, you can top up for free.
