The real challenge in Tetrix Online is staying one step ahead of the falling blocks. You have to constantly clear horizontal rows to keep the stack from reaching the top of the Matrix. As you level up, the speed ramps up fast, so sharp focus and quick decisions are a must if you want to survive.
The fastest way to rack up huge points is the legendary 4-line clear. Smart players keep their stack nice and flat while leaving a single empty column on one side. When the straight “I” piece finally drops, slam it in perfectly and watch four rows disappear at once for the biggest score bonus in the game.
Keeping an eye on the Next Queue lets you plan several moves ahead.
