Heads and Tails reduces a round to a two-sided coin prediction. The coin's Bitcoin and circuit-board designs identify the two selectable sides; they are not slot symbols or bonus triggers. A successful prediction is settled at the game's stated return, rather than activating paylines or free spins. A 50/50 outcome distribution also does not automatically mean an even-money payout or a game with no house edge.
