The five-by-three grid was designed for landscape screens and predates phones as the dominant device. What happens when it is placed in a portrait window is a compromise, and how a given build handles that compromise varies more than it should.
The geometry problem
A wide grid in a tall window either shrinks to fit the width, leaving substantial empty space above and below, or it fills the height and overflows horizontally. Neither is good, and the usual resolution is the first.
The consequence is small symbols. A grid occupying a third of the screen height on a phone in portrait puts fifteen symbols into a strip, and legibility suffers directly.
The rotation question
Landscape solves the geometry and creates a different problem: controls compete with the grid for the same limited height, and one-handed operation becomes awkward. Some builds handle this well and some simply scale the desktop layout down.
Checking it directly
Load it on the actual device. Opening the Thai Temple demo on a phone in both orientations and looking at a resolved grid in each settles the question in under a minute, and the answer will not change with familiarity.
Test the paytable in both orientations too. A panel laid out for a wide screen and reflowed poorly is a panel that requires pinch-zoom, and a paytable requiring pinch-zoom is one nobody reads.
- Load in portrait and look at a full grid
- Rotate and compare directly
- Open the paytable in both orientations
- Check the spin control is reachable one-handed
- Confirm the stake control is not adjacent to spin
The control adjacency check
A stake control beside the spin button will eventually produce a round at an unintended amount. Whether the build guards the change with a confirmation is worth one deliberate test before it happens accidentally.
Where older builds struggle
Titles designed when desktop play dominated were adapted to phones rather than built for them, and adaptation shows. Larger touch targets, reflowed panels and orientation-specific layouts came later, so an older build may work while still feeling like something scaled down.
Why the check belongs before the session
Because most play happens on phones and most assessment happens on desktops, and that gap accounts for a good deal of avoidable disappointment. Two minutes on the device that will actually be used closes it entirely.
