MagmaRush puts a cross-section of volcanic rock on your screen with a glowing vent at the top pouring molten lava continuously through branching crack channels. Three diamond-shaped junctions split the flow — each one routes the lava left or right into the next branch. Tap any junction to flip its direction and redirect where the lava goes. Four collection chambers sit at the bottom of the rock face, each marked with a target fill line. When you think the lava has reached the right level in a chamber, tap it to lock the amount in and score. Get it close to the target line and score points. Hit it perfectly and score double. Let a chamber overflow past the safety margin and lose a life. Route all the required chambers to their targets to clear the level and move on to faster, tighter challenges.
