Played only one game so far, but I liked it.
I will say it isn't what I expected. I thought it was going to be more like a hexagonal version of 2048, and while there are minor similarities, it is pretty different.
First off, turns are not about all the pieces moving in one direction, but picking one piece and moving it.
Second off, it works on multiples of four, so half you pieces can never merge with the other half. Fours become sixteens becomes sixty-fours, etc., while eights become thirty twos which become one hundred and twenty eights.
That said, it is still fun and clever.
For starters, as long as you can make groups of four, no new pieces are added to the board, as soon as you cannot, five more are added to the bottom. You can see what numbers are coming, which is a little useful, but near as I can tell, placement is random into empty spaces. It can help you decide which not matching move to make, as newly dropped units will merges groups of four if it matches.
Note that if you can make a larger group, a set of five or more, they all merge, but the total remains four times the amount on one of the tiles. This still opens up more of the map, so that is still a good thing.
There are also two tactical actions you can take, shuffle and a bomb which takes out one space. These cost you energy, which defines how many moves you can make before the game ends.
Making a match will add one energy, so eventually you will run out.
I get the impression that faster actions might give you more energy in a combo, I need to experiment more with this.
There are a few oddities, for example most of the time the four will merge into the space where you placed the last tile, but not always, not sure why.
All in all though, I had a lot of fun, and easy two thumbs up. Thinking about maybe making a guide? If you want a basic guide, drop a comment here under my review.
