that argument comes over Websocket - either from my Android app,
or from my HTML5 game at https://slova.de/words/Words.js (just an array of
objects, stringified):

var tiles = [];
for (var i = boardTiles.length - 1;
i >= 0; i--) {
var tile = boardTiles[i];
tiles.push({
letter: tile.letter,
value: tile.value,
col: tile.col,
row: tile.row
});
}

var play = {
social: SOCIAL,
sid: SID,
auth: AUTH,
action: 'play',
gid: gid,
tiles: tiles
};
ws.send(JSON.stringify(play));
