The Mobile Game House of Cards Made Famous Just Dropped to 99 Cents

If you haven’t heard the chorus of praise for Monument Valley, the mobile game that TIME ranked among the 10 best games of 2014, now is the time to take note. The sleeper hit from indie game maker UsTwo —which has developed a cult following of diehard fans, including President Frank Underwood from Netflix’s original series House of Cards, who can’t get enough of it—is now on sale for a new low price of $0.99, down from $3.99, in the iTunes and Google Play stores. Puzzle addicts, buy at your own peril.
