Almost nothing in Profile changes the game. It changes how the game looks, sounds and feels in your hand — and one setting at the bottom of this page is the exception worth knowing about.
“Blocks” sets the shape and colour your cells are drawn in, and a colour can be fixed or fresh every game. “Look” chooses bright or dark whatever the phone says. The avatar can be a photo instead of your initial. None of it changes how the game plays or what anything scores.
The music and the sound effects are separate switches, because a click when a piece lands and music under the board are different tastes. The music is guitar recordings in the public domain, taking turns over a river with quiet water in between — the button beside its switch says who plays them. The speaker on the game screen steps through both together, so you seldom need to come here for it. Vibration is its own switch too, so it still works with the phone muted. “Full screen” hides the clock and icons and gives the board the height. All preferences: turn any of them off and it is the same game.
Google Play installs updates on its own, but it can take three or four days to reach a phone. So when a newer version is out, a bar appears at the foot of the start screen and one tap fetches it straight away — the game keeps running while it downloads, and it asks before restarting. Turn “Update reminders” off and it stops appearing; an update you already started is still shown, so it cannot be left half-finished.
The flag at the top of Profile and the flag in the corner of the start screen are the same control, and each language is named in its own words. Switching is instant: a game in progress keeps going and the screen simply changes language under your finger.
This is the one setting that changes how the game answers your hand. A dragged piece rides ahead of your finger, and this decides by how much — which is what makes the far side of the board reachable at all. With none of it, a thumb anchored in the corner of a phone cannot get there. With too much, the piece appears to be fleeing your hand.
There are two sliders because your grip changes when the device turns: one for upright, one for on its side. Neither is a rule and neither has a right answer — only the one that suits your hand. That is also why the landscape slider is repeated on the game screen itself: this is not a thing anybody can judge from a menu. Drag a piece, miss, and adjust.
