// How ReelTime works
// ==================
// Entering ReelTime:
// - If the bias you draw at the start of the round is BIAS_REELTIME, the
// ReelTime lottery begins.
// - At the start of the lottery, the game selects how many ReelTime spins you
// will get, based on how many Power bolts you've collected and whether it
// is a lucky game.
// - The lottery machine rolls until it lands on the selected number. If it
// selected 0 spins, the lottery machine will mostly likely explode before
// landing on 0.
// - If you win:
// - You receive the selected number of ReelTime spins
// - You lose all the Power bolts you've collected thus far
// - The lottery window closes and ReelTime officially begins
//
// During ReelTime:
// - You still have to pay coins for bets.
// - The slot reels may spin slower than usual in ReelTime. The machine draws a
// reel speed at the beginning of each ReelTime spin. The more coins you've
// lost to the machine, and the more consecutive ReelTime spins you've done,
// the higher your chances of getting a slower reel speed.
// - In ReelTime, the reel stops exactly on your input. That is, it won't add
// extra turns to manipulate the outcome.
// - ReelTime ends early if you win red 7's or blue 7's.
// SlotMachine field explanations:
//
// luckyGame:
// Determined at random when you start playing. Some events modify this:
// - Blue 7 match: game becomes lucky
// - Red 7 match: game becomes normal
//
// Effectively, a lucky game inreases the odds of getting more ReelTime spins.
// If the game is lucky, you have a slightly higher chance of matching Power
// bolts (at the expense of Replays). This helps you fill your Power bolt
// gauge faster.
//
// During ReelTime, the more Power bolts you have, the greater your chances
// of drawing more ReelTime spins. In a lucky game, you have greater odds of
// drawing high yields (3+ RT spins). You also have greater odds of drawing 0
// RT spins. But drawing 0 lets you keep all your Power bolts, allowing you to
// fill your gauge further.
