IVY

Ivy is a quick, tactical puzzle game, easy to pick up and tricky to put down.Place your numbered cubes on the grid, building lines to force your opponent into picking up more. Get three in a row and they take a cube, more for them to shift and less for you. Empty your hand before they do to win. Think Connect 4 meets dominoes, with a twist.Build bigger lines and the rewards grow. Five in a row lets you throw a cube away, seven gets rid of two, and every two after that removes another. String together a big enough line and you can clear your hand in one move.Simple to learn, surprisingly hard to master, with quick levels you can blast through in a spare moment or chain together for hours.As you progress through hundreds of levels, the challenge builds. Water tiles block where you can place, bombs blast cubes clean off the grid, and quicksand slowly swallows anything that lands on it. Finding a path through takes more thought than it first looks.Ivy started life as one of the games in the Cube Roots collection, a set of 216 sustainably-produced wooden cubes designed to play a huge variety of games. Now it's on your phone, with the same core idea: a small ruleset, a lot of depth, and no unnecessary clutter.
