Yeah, Row shift started bugging out on me as well on 12-29, where blocks would be pushed down one row and keep shifting to the right each move, resulting in blocks overlapping the same position. It caused me to fail a couple of times. There were also a few instances where the game denied me from making a legal 3 combo in world 12 (in general; 100% positive), though in the end I don't think it would have led to the correct solution.

For the random levels, I've been taking a picture of a puzzle on my phone and then solving it when the game is paused. My phone allows me to draw on the picture so I use dots and numbers to keep track. Just keep in mind of the modifiers, this method doesn't really work on the row shift puzzle unless you're good at remembering everything.

What is with the row shifting level!?

The row shifting level is a bug, as far as I know they were looking to fix it on Steam but I don't know if they ever learned about it on the Xbox.

Any tips for 12-30? It's so damn random.

After numerous attempts, I finally finished 12-30, but the AI was so random. Sometimes I thought I was doing really well on a puzzle, but the AI finished when I was only half done.
When I finally finished it, I had 4 wins, and I got to a puzzle that the AI couldn't seem to solve. There were only two colours, but with sprouts, the alternating grid locks, and I can't remember the last one.

It still took me about an hour of failing to finally get it, but damn it felt good.

For 12-30, I'd say stick to what you know about certain modifiers even when paired with some hard ones. You know that the beehive modifier you need to finish the puzzle with all columns, you know that the 3-2-1 step modifier needs to be done one row at a time and you always need to look out for the next color you want to grab. Double shot means you should be looking for groups of colors. For wildcards, you try to pretend that a certain wildcard is already a specific color if it is surrounded by that color. Pretty much play to your strengths, as you most likely won't win all 5 in a row. Also if the AIs get a few wins and you don't have any, you might as well restart to put you on an even playing field. Though, you shouldn't restart if you already have a few wins because you never know what could happen.

The 12 random levels challenge isn't too difficult if you pause to analyze each segment for blocked colors before starting. Each puzzle by itself is a low to medium difficulty puzzle for each world's modifier, so it's not too bad if you stay calm.

The real problem is the 12-10 and 12-30 puzzle races that can't be skipped. The Sparring bots are already tough enough to beat with 2-3 modifiers each round, seeing as how you have to pause and scrutinize each move while the AI doesn't miss a beat, but the real problem is when the Sprouts modifier shows up. On 12-30 in particular, since it uses 3 mods each round, the Sprouts mod can make a puzzle so difficult that you or the AI won't be able to solve it at all. This happened to me at least twice, where some combination involving Sprouts caused the round to go on for an HOUR without anyone solving it. It doesn't happen every time it shows up. Just certain combinations (which I didn't take note of, but I feel Staggered Locks might have been involved.) So, sometimes it's best to just give up and start over, especially if you don't have a lead or are on 3-4 wins.

I just used a skip token, thanks to your other really great guides I have loads of them spare!

do skip tokens count towards the achievement? I'm about 20 levels from the end and I have all 11 skip tokens... does this mean I only have to do 9?

Thank you albinoKidELITE and yeah beatmoah if you want to use skip tokens you can it'll save you a little bit of time

Can you use skip tokens on the random generated levels without it affecting the achievement? If YES i'll be stockpiling those babies lol
