Containment

Containment is an arcade game with 80 levels across four phases. You control four paddles, one on each edge of the screen, to keep a ball in play and contain and destroy the bricks before they drift off-screen or touch a paddle. The mouse moves all four paddles: the left and right paddles follow its up-and-down movement, while the top and bottom paddles follow its left-and-right movement.

Levels and bricks

The 80 levels are divided into four phases, each introducing different 3D brick shapes. The phases begin with rectangular and square-faced bricks, then add pentagonal bricks, hexagonal bricks, and finally spherical and ovoid bricks. These shapes are mixed together in increasingly complex levels. Initial levels include helper blocks that cover random sides, letting you focus on the other edges while learning to control the four paddles. These blocks appear only in the initial levels.

Stars and crowns

To finish a level, you need three types of stars: Time Left, Lives Lost and Bricks Lost. Each star type has Bronze, Silver, Gold and Platinum ratings. A level’s crown is based on the lowest rating among its three stars: for example, two Bronze stars and one Platinum star earn a Bronze Crown. You need at least a Bronze Crown to unlock the next level, while the Platinum Crown is the highest possible achievement for a level.

Power-ups

The game has 20 types of power-ups, some of which can be combined into powerful combos.

Save files and stats

There are three save files, and progress is saved automatically between levels. Progress within a level is not saved if you exit before completing it. The game stats page also saves totals such as play time, lives lost and power-ups collected.
