I've seen discussions here and elsewhere about aphantasia, the inability to have mental imagery. One thing that strikes me is that they've been mostly about reading fiction, about whether some of us are having a mental movie playing as we read. It's the sort of unreachable subjective experience that's hard to compare, leaving open the possibility that at least some people are having the same experience I am but labelling it differently: I would say I have imagery, but also that it's vague and ghostlike, not at all like hallucinating a full color experience. (I'm also not sure how much I spontaneously 'movie' my fiction, vs. sometimes making a deliberate effort to visualize a scene.)
But there are things I do with my imagery which have measurable outcomes. Most trivially and accessibly, I can play out a game of tic-tac-toe in my head, or play it blindfold, and I would be indeed visualizing a board and 'seeing' whether rows are completed, not doing math on a list of coordinates. I can imagine trying to play blindfold chess though I expect I would be overwhelmed by the detail[1]. I can do multi-digit multiplication or long division in my head much as I would on paper, 'writing' the numbers on mental scratch paper and remembering their positions. I've discovered geometry proofs in my head, and I can run a simple orrery of Earth and Moon motions around the Sun, to explain why the phases of the Moon look the way they do or why most artificial satellites rise in the west.
So for aphantasia people... are these things you simply can't even attempt? Or would you do them differently? I can maybe imagine less visual approaches to the arithmetic, and maybe a numeric coordinate-based approach to tic-tac-toe or even chess, but the others seem inherently visual. Naively, asking whether you can do visual tasks seems more definitive than asking how vivid imagery is.
[1] Chess masters are said to rely on high level functional grouping of pieces, and the experiment behind that is somewhat relevant: asked to look at a board and reconstruct it from memory, they do quite well if it's from a real game and thus makes sense, but on random boards they do no better than the rest of us.

If you play ttt in your head, how would you describe if it not visual? Tactile? Spatial (awareness of location of objects)?
I still wonder if some of us are having similar experiences (awareness of shape and location, say) but interpreting/labeling them differently (visualization vs. something else.)

Does the sun tend to rise and set in the correct directions in your dreams?
My dreams generally don't have correctly oriented suns (most recently I had a dream involving being caught off-guard by a solar eclipse while trying to figure out bus schedules, and when I woke up it occurred to me to put two and two together with [the place and time provided by the bus schedules] and [the sun] and work out that it was rising in the northwest), and I'm curious whether being more able to grok the movements of major celestial bodies has helped you with that sort of thing.
