New coins are minted after every 2 or 3 moves, depending on difficulty. You can keep tabs on them at the bottom of the screen (Red bar - 1 move, Yellow bar - 2 moves, Green bar - 3 or more moves) and strategize accordingly. If a column of coins reaches the top of the screen, you'll get a warning, the coins will flash, and you will need to remove enough coins to get back to a safe height. If you can't make a move, your game will end!
Robo-advisors are diversified investment accounts that are automatically managed by a computer algorithm (as opposed to a human money manager). If you want to invest, but don’t have the money, or don’t want to invest with a money manager, robo-advisors are for you! Robo-advisors make investing easier—and cheaper—so they’re perfect for new investors.
