Some what frustrating in that I had to slowly figure out the merge rules for points. But maybe that is because I am new to this.

The ad I responded to showed a completely different game that tested your ability not to cross lines. What downloaded is nice but not what I selected.

I like. Enough to engage but not stressful like some games that speed up.

Okay with it. Good for tuning out.

Tetris(tm) descendent games are difficult for people with hand disabilities. There should be a warning. I picked this because it was pins, then it forced me to do speed Tetris(tm) so I am deeply disappointed.

Probably fine for someone with fast hands. Not me, I can't do increasing speed any more and they don't have a shut off. Socks having essential hand tremors. Wish some of the Tetris(tm) descendents took the disabled in mind. So keep us out of tournaments dependent on speed.

So far good. It's nice not to have to work against a timer, just my self.

I initially scored this game high. However the timed tetris-like challenges truly frustrated me. I use to love thes but due to physical issues cannot succeed at certain speed horizons and thus can no longer progress. Hence no more playing.

Finally a game that does not bait & switch on the type of challenges.

at start seems fun

This awesome. Doing math this way is opening up capabilities I long thought gone. Much Better than sudoku.

Good for blanking out noises
