just keep tyrying different cards come up its all about chance
if theres a space try and take away the top row this way you finish the game quicker as it drops the other balls
try to see which cards you can put on each other to leave a cap theb you will have an extra place to build a column
if you have a big space between the balls get two colours the same at ends nearest to each other itll pull the balls back which gives you more time
got up to 98 then it kicked me out of the game without saving me score
