Tile puzzle for me. I'm not a big fan of the other ones, and I'm definitely better at tile puzzle than I am at the others (though I don't play any of them that much).

My favorite is definitely Berry Picker. It's like I'm helping my babies get something healthy to eat before feeding them all of those super pokepuffs. :P
Head It is fun too, but I hate that large ball of yarn at the end. I swear I've gotten worse at that part over time, I can never hit it anymore.
As far as Tile Puzzle, well... I hate it and it hates me.
My favorite is Tile Puzzle, but I suck at it XD. Since I only earn like 4 Pokepuffs max on that game, I usually play the other two. I'm best at Berry Picker, so that's my second favorite. o3o
Really don't enjoy berry picker, head-it unlimited is best for me. Easy to gain puffs and still challenging every time. Tile puzzle is for when Head-it gets boring :)
Berry Picker unlimited was the only one I'd play for a while, because it came easy to me. But now it's gotta be Head It unlimited. There is something fun about bouncing yarn balls about on Pokemons' heads, I suppose.
Head it, I'm not very good at Berry Picking and I just cry in shame at my preformance in the tile puzzle. So far my head it high score is something like 520 on the hard mode. The tile puzzle I tend to find I'm horrible at as the stuff in it moves, throwing me off.
