+		<p>The three boards stand one above the other, the air at the top, the land in the middle and the underworld at the bottom, in the colours Gygax suggested. Your side is nearest you on every board. Each piece is a disc bearing the initial Gygax gave it, with Dr for the Dragon so it is not mistaken for a Dwarf. The square names along the edges are his too, and you can hide them under <em>preferences</em>. A square is named by its board, its file and its rank, so 3b4 is the air, file b, rank 4, and 1g1 is the underworld beneath Gold's King. Each board's title carries its number.</p>

 		<p>Tap any piece, yours or the other side's, and a panel opens beside the boards, or rises from the foot of the screen on a phone, saying what the piece is, where it stands and what it can reach from there, how it moves, why Gygax put it in the game, and how to play it. Dotted squares show where a piece that is not yours to move could go. Tap the piece again, or the cross, to close it.</p>
 		<p>The strip above the boards says whose move it is and warns when a King is in check. The chronicle beside the boards tells each move and what came of it, who took what, whose gaze fell on whom, and when a King is in check, with Gygax's notation beside each move. Click a move to see it on the boards, and click again, or make your move, to come back to now.</p>
