I've done the research.

Here are the best ways, in my mediocre opinion, to play each comp. Words: iPad because the screen is so tiny mobile Lucky Drop: Computer because my computer is luckier than my phone Deal: iPhone because my iPhone is luckier than my computer Holey: computer, if you're playing mobile...like what...how? Match 3: iPad, I tried this today and got my best score Chainpop: iPad because the balls are bigger Starfall: iPad, less fear of swiping out the comp Stacker: computer but I have to make half the screen disappear at the bottom Codebreaker: iPhone so you can click fastest Shapes: iPhone, just focus on the colors Weightlifting: laptop arrow keys - superior Guitar: nothing, fuck this comp Flags: anything, study
