Tilt Box is a marble rolling puzzle in which you never move one marble at a time. Each move tips the whole box one way, and every marble rolls until it hits a wall or another marble. Use the arrow keys, WASD, a swipe or the on-screen pad. A move that shifts nothing is a free bump.
A coloured marble that rolls over a pocket of its own colour and shape drops in and is gone; other pockets it simply rolls across. The bomb is different: it drops into any pocket, and that ends the attempt, with undo on offer. Sink every coloured marble to win. Each marble and pocket carries a shape as well as a colour, so the board reads without colour. After every move the game checks whether the box can still be finished and warns you if it cannot.
Par is the fewest moves. Matching it earns three stars, and up to two over earns two. Undo is free. The hint shows the next move on a shortest route and caps the level at two stars. Sixty boxes run across five tiers, with a bomb from the second tier and more marbles later, plus a daily box.
Worked example
The bomb starts directly above two red pockets, so a move down would drop it in. First roll it into a nook with a wall beneath it, where a downward move cannot shift it. Only then is it safe to send the red marble down into its pocket.
Strategy tips
Use marbles as stoppers. A marble resting against another stops short of the wall, often exactly where you need it.
Park the bomb first. Find a square where the bomb cannot roll into a pocket, and get it there early.
Think in pairs of moves. A move away and back again rarely returns everything to where it was.
