Knock Out is a free block-shooting puzzle game for Android with over 1 million installs on Google Play. Combo Game released it on June 29, 2026, and the current version is 2.4.0. Players fire blocks at structures and try to clear every piece from the board.
Combo Game and the project behind Knock Out
Knock Out comes from Combo Game, a developer that runs its own site at combo-games.net. The game sits in the puzzle category and carries an Everyone content rating on Google Play.
It is a young title. The first release dates to June 29, 2026, and the latest update landed on November 4, 2026. Google Play shows a 4.7 rating from about 9.9 thousand ratings.
Shooting, toppling and chain reactions
Each level asks you to fire matching blocks at towers, obstacles and other constructions. The aim is to knock everything down, and well-placed shots set off chain reactions driven by physics.
The store text describes hundreds of handcrafted levels, each with its own structures and objectives. Visuals are colorful 3D, and controls focus on precise single shots. Because the game works without an internet connection, you can play it offline.
Monetization comes in two forms: the game shows ads and offers in-app purchases, although installing it costs nothing.
Android 7.0 minimum and what to expect on your phone
Knock Out needs Android 7.0 or newer, so it runs on a large share of older handsets. The package name is com.combo.knockout, which helps when you search for the exact title on Google Play.
Eight screenshots are published on the store page for a preview of the 3D look before installing.
