WHAT IT IS
Cubes 2 in short
Cubes 2 is the February 2021 sequel to Hacksaw Gaming's Cubes, and the idea is the same: a 5 by 5 grid of coloured cubes that grows a ring every time a cluster wins, out to 11 by 11. The sequel turned the volatility up from medium to high, put the cap at 10,500x and added the colour blast jackpots, which pay for counting cubes of one colour across the whole expanded grid. The published RTP is 96.30%.
Canadians search for it because it looks like nothing else in the lobby. No reels, no theme beyond the shapes, no music that sticks. People either find that restful or boring in the first minute, and that decides whether they stay.
HOW IT PLAYS
Base game and symbols
Five or more cubes of one colour touching horizontally or vertically form a cluster and pay. After a win the grid grows one ring in every direction, 5 by 5 to 7 by 7 to 9 by 9 to 11 by 11, and the winning cubes are replaced. More cubes means more clusters, and a spin that reaches 11 by 11 can chain for a while. If a spin ends with no new cluster, the grid shrinks back to 5 by 5.
The corners carry X symbols. When a cluster reaches a corner X, that X becomes a multiplier equal to the size of the cluster, so a nine-cube cluster into a corner is 9x on that win. On the full 11 by 11 grid the corners are far apart and the clusters that reach them are big, which is where base-game wins of any size come from.
The pace is odd. Small-grid spins are instant; a big expansion takes a minute to play through. On C$0.40 a spin a C$30 session is plenty of time to see the grid fill. Most casino bonuses cap the stake at about C$5 to C$7 a spin and exclude both buy options, which cost 129x and 109x, so on bonus money you wait for the triggers, which land roughly once in 223 spins by the published figure.

THE FEATURE
Bonus round
Five cluster wins in five different colours during one spin start the free spins. You pick one of five cubes to set a sticky colour, and the grid does not reset between spins. The colour blast jackpots count cubes of the sticky colour on the grid: 500x your stake for 50 of them, 2,500x for 70 and 7,000x for 90, which on an 11 by 11 grid of 121 positions is most of the board. That is where the 10,500x cap comes from.
The multi colour bonus starts when all four corners show the same colour on a base spin. You pick cubes for up to four sticky colours and get five to ten free spins with the corner multipliers instead of the jackpots, capped at 7,500x. A dead round is a grid that never gets past 7 by 7, a sticky colour that lands in ones and twos, and a return under 10x on a 129x buy.
OUR TAKE
Should you play Cubes 2?
Play it if you want something that does not look or feel like a slot, you like watching a board fill, and you have the patience for a bonus that is all about reaching a count. It is a real-money game with a reasonable buy price. Skip it if you need a theme or a feature that pays early. For a Hacksaw cluster game with more going on per spin, Stack 'Em is the pick, and Reactoonz is the other grid game with a collect meter people compare it to.

It starts at 5 by 5. Every winning cluster adds a ring of cubes around the edge, so it goes 7 by 7, then 9 by 9, then 11 by 11, and more cubes mean more chances for clusters. A spin that ends without a new win resets it to 5 by 5, except during the bonus rounds.
02Can I play Cubes 2 with a casino bonus in Canada?
Usually, with the stake capped at about C$5 to C$7 a spin and both bonus buys excluded while bonus money is active. The game has several RTP builds, so open the info page and check for 96.30% before using bonus money. High volatility makes it a slow wagering choice.
03What are the colour blast jackpots?
Fixed prizes in the free spins for how many cubes of your sticky colour sit on the grid at once: 500x your stake for 50, 2,500x for 70 and 7,000x for 90. The grid holds 121 cubes at full size, so 90 of one colour is a nearly full board and very rare.
