A well ten wide and twenty deep, at night, and four-block pieces falling into it. Turn them with a tap, move them by dragging your thumb, drop them with a flick: every full row lights up and melts away, and the pile must not reach the rim.
Tap to turn, drag to move, flick down to drop. 
Four rows at once are worth twice four single rows. 
The well turns from lime to ember as the pile climbs.
What it does
- Seven pieces, dealt seven at a time: no more than twelve others between two of the same kind, and the long one never vanishes for half a game.
- Thumb controls over the whole play area, not just the well: the piece moves one column for every cell of travel and stays under your thumb at any speed. Prefer buttons? There are four big ones under the well.
- The ghost shows where the piece will land, the next three are already in sight, and the hold slot keeps one piece aside for when you need it.
- Points by level: 100, 300, 500 or 800 for one, two, three or four rows, times the level. The level goes up every ten rows, and the fall speeds up with it.
- Pauses by itself when you leave the app or pull down the shade, and only carries on when you tap.
- In English and Italian, following the phone's language.
The piece turns even against the wall
A piece pressed against the wall or the pile, with no room to turn where it is, tries up to five nearby positions — a column over, a row up — in the order experienced players already have in their fingers. It is the difference between a piece that "won't turn" right at the right gap and one that slots in. And resting on the pile it has half a second to be adjusted before it locks.
Your data stays yours
Stack asks for no permission beyond the ads network and the vibrator. The best score and the haptics switch stay on the phone: there is no account and no online leaderboard — that would be a server, and we have none.
How it pays for itself
With a banner anchored at the bottom and, now and then, a full-screen ad between one game and the next, never while pieces are falling. No subscription, no lives to buy, no waiting.
