Board Game Arena

i was physically unable to "place a tile" tried everything with my touch pad and my enter button. could not figure it out. i've played this game physically before but never on line. how as in what computer keys do i hit to "place a tile?" thks meb

Not sure how it looks on a tablet, I use a laptop.

1) You first click an area of the board to select the region you wish to place the tile, and a transparent version of the tile appears.
2) You can then rotate the tile with the mouse until you see the orientation you like.
3) Click a second time to place the tile. Or if you don't like the region you picked, go to step 4.
4) If you don't like the region you selected with click 1, click that starting point again to deselect. Go to step 1.
