One rotation, then hold the face
Tube Rush puts you inside a hexagonal 3D tunnel. The tunnel comes toward you. Tap left or right, or use arrows and A/D, to rotate one face. There is no jump and no brake. A missing panel is the open lane. A solid panel that reaches you is a hit.
A hit costs a life. Three lives. Each gap you pass scores, and consecutive gaps multiply. Later rings arrive faster. Combos are entertainment. They have no cash value and do not restore a heart.
A closed panel is a hit
Look at the next open face, not the wall beside you. Rotate once, then hold. Spinning every frame is how a sitting becomes a slot. If the loop feels urgent, that is by design—set a timer before you start, and honor it.
The 3D camera is a depth cue, not a crash movie. We did not add wrecks or a ship shop. If perspective motion makes you dizzy, pause or pick a still puzzle. The title is rated 8+ for cartoon peril and motion, not as a babysitter. It is not directed at children under 13.
Stop when the hex starts nagging
Gap Drop is the flat cousin: one hole in a falling wall. Lane Switch is three labeled roads. If you wanted those, open them. Tube Rush is for people who like naming a face in a hex and who can close the tab when the chain starts asking for one more try.
Drill: six rings with at most one rotation each. Count clears. That count is the practice score, even if the combo never got large. Stop when the drill is done.
