Any puzzle in the easy, normal or hard set is solvable entirely by logic. If you're stuck, you probably need to solve the corners. Let's say the bottom row starts with 8. If you assume the bottom left corner is a pixel, then the 7 next tiles would be pixels. Work up the clues for those 8 columns and the bottom rows. if you get a contradiction, that corner is an X. Then restart for the next tile. It's really time consuming, but some puzzles require it, or at least I didn't find another way myself.
@zomg1234567891011 Your computer has a problem too then. Right click the game and set storage to unlimited. If that's not it, enable cookies. Otherwise, google to figure out your issue with Flash.
@Desukitty If you're relatively new to the game, you probably got the triangle trinkets from the Strange Box monster. It appears in the Battle Arena's main path areas (stuff like Desert, Beach, etc.). A quicker way to get them is fighting in Triangle Land, but you need a high level.
I'm not sure why you guys lag so much, but it might be a Flash Player issue. If you play on Chrome, go into your plugins and make sure you don't have two Flash Plugins enabled at once, one by Chrome (PepperFlash) and the normal one on the computer. I chose to have PepperFlash enabled and the controls respond correctly for me. Leaving both enabled creates massive lag.
The early levels are way more strict for A+ times than the later levels actually. World 3 has fairly lenient A+ times for how hard (or random) the levels are. You can barely wait for anything in the early levels, but fortunately you usually avoid everything by moving forward nonstop anyway.
If you have a lot trouble with the 100x multiplier badge or the 5.000.000 points badge, you might be lagging. If you lag, less shapes appear. After setting the quality to low and closing all other tabs, I easily got over 6.000.000 , while getting 4.000.000 before required a lot of luck, mostly because of Yellow Madness.
The most important thing for the impossible badge is having good arrow keys. If you don't have good arrow keys, use a key remapper to set other keys instead (I used UHJK, but WASD would be make more sense I guess). Level E requires diagonal input and quick, small taps to truly have any kind of control.
