+// Crazy Time is a single-seat betting wheel modelled on Evolution's game of
+// the same name. The main wheel reuses Big 6's physical-wheel structure and
+// animation; it can stop on a number (1, 2, 5 or 10) or on one of four bonus
+// games (Coin Flip, Cash Hunt, Pachinko and the Crazy Time wheel). Every
+// bonus is a pure multiplier generator: it only ever returns a positive
+// multiple of the bonus stake, because the house edge lives in the main
+// wheel's probabilities, not in the bonuses.
+//
+// RTP is exactly 98% for every betting target. The main wheel alone would
+// return far less, so each round also spins a "Top Slot": it picks one of the
+// eight symbols uniformly and a multiplier from that symbol's own
+// distribution. If the main wheel then stops on that symbol, the win is
+// multiplied. Each symbol's multiplier distribution is tuned so that the
+// combined return is exactly 98%.
