Tips for people
I like the puzzles and pretty stones. However, there were some levels where it's hard and doesn't give me enough time. Overall, it's still an enjoyable game.
For people who have ads problem while playing this, play it OFFLINE. Mochi ads can't get to you without the internet. Don't berate the game just cuz of ads.
Anyway, here are some tips I found while playing:
1) Plan ahead. It's a puzzle and the timer won't start till you start sliding. Take your time to study the puzzle and all of its obstacles so that you may think of a way.
2) Designate the spots to gather your stones. If you see a group of one colour near to each other, that'll be the most likely best place to gather them. Unfortunately, the trapped stones are bitches...
3) Fill up the corners. It's not only tidy, it also eases movement. However, you gotta be careful in levels that are narrow and/or have annoying weirdly shaped blockers. Those are really annoying... This tip is in conjunction with tip #2.
4) For those who are aiming to unlock all stones, there are times where you just gotta slide the stones and see where they'll go. Trial and error methods are good to find out about hard puzzle levels. This is especially those that are narroe, have blockers, and shorter time records. Then when it's all sorted out, you can try doing it to beat the time record and get your pretty bling-bling.
Hope these tips help people. I'm still to unlock some stones I skipped.
