Keyboard, Controller or Touch?

The input device matters less than people claim, but it matters in specific and predictable ways.

Every input method can be played well. They have genuinely different characteristics, and the differences are narrower than the arguments about them suggest.

Keyboard

The standard for serious play. Keys are independent, so pressing left and rotate simultaneously is trivial, and the travel is short enough that fast sequences are comfortable.

The main weakness is that most keyboards limit how many keys register at once, which very occasionally drops an input during a fast combination.

Controller

A d-pad is more comfortable for long sessions and easier on the hands. Face buttons for rotate are more natural than reaching for Z and X.

The weakness is directional precision. A d-pad pivot can register a diagonal you did not intend, and analogue sticks are worse. Competitive players on controllers almost always use the d-pad.

Touch

Genuinely viable, and better than its reputation, provided the implementation takes it seriously. Gestures are fast for movement and rotation; the difficulty is precision, since a finger occludes the thing it is pointing at.

TETERI supports both gestures and on-screen buttons at once so you can mix: swipe for coarse movement, tap the buttons for single-cell adjustments.

Gamepad on a phone

The best of both, if you have one. A Bluetooth controller paired to a phone gives you d-pad precision on a screen you are already holding.

What actually matters

Whichever you use, two things dominate:

Consistency. Switching devices constantly means never building the muscle memory that makes finesse possible. Pick one for a while.

Tuned auto-shift. Overshooting by one cell is the most common input error on every device, and it comes from holding a direction fractionally too long. Tap for small moves. This single habit outweighs the choice of device entirely.

The honest summary

Strong players exist on all three. If you are stuck at level nine, it is not the controller.
