Steam Tower on a phone
You can run this one-handed on a bus. 2.9 s to load, portrait holds, tight buttons.
The phone check
Upright, the spin button shrinks and the bet stepper crowds it. A wide thumb hits the wrong one. The demo pulls about 12 MB before the first tap registers, which on a poor bar is where the 2.9 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 97.04%. 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 188 of 306. Orientation carries the most weight, the wait carries the next, the buttons carry the rest. The board median is 2.1 s, so this one costs you an extra 0.8 s a session.
NetEnt has 24 titles on this board, 14 of them upright, with a median load of 2.6 s.
What the game is
Out in 2015. NetEnt built it as 5x3, 15 lines with stacked wilds / tower climb. Steampunk rescue mission where stacked wilds launch free spins and every wild climbs the tower toward multipliers up to 7x.
Volatility reads medium, so the balance moves in lumps, and fifty spins will mislead you either way. Minimum stake is C$0.15, which is about 133 spins on a twenty. Ceiling is 2,000x and it is not going to happen to you.
