Finn and the Swirly Spin on a phone
Sideways or nothing. 2.6 s to playable, and the rotate prompt shows up before anything else does.
The phone check
Sideways is the only layout and the buttons are built for it. Fine in two hands, awkward hanging off a pole on the subway. The demo pulls about 11 MB before the first tap registers, which on a poor bar is where the 2.6 s goes. Getting money back out is a separate count and we keep it at cashout.
One build, one return figure
NetEnt licenses a single build of this one, at 96.62%. The figure in the game's rules footer will match the figure above, every time. That is not true of the 123 titles here that ship in more than one configuration.
Where it sits on the board
On the phone score it lands 281 of 306. Orientation carries the most weight, the wait carries the next, the buttons carry the rest. It runs 0.5 s over the 2.1 s board median, which you notice on a weak bar.
For context, 14 of the 24 NetEnt games on this board hold portrait and the studio median is 2.6 s.
