Fifteen pieces of a games night: Dice, DiceTray, PlayingCard, CardHand, Deck, Chessboard, GoBoard, MahjongTile, Domino, Roulette, CoinFlip, BingoCard, TicTacToe, ScoreTrack and Meeple. Component number 500 is a meeple, which seems right. Dice tumble, coins turn and wheels spin on a cue, a frame at a time, and land at once under Reduce Motion. Hands lift the card you point at and play the one drawn on top; pieces and stones pick the lighter of Lit and Ink for White, so they read in every palette; the computer plays a fair O; FREE is a star in every language. New 12x12 icons: Spade, Club, Diamond, Meeple, King, Queen, Rook, Bishop, Knight and Pawn.
