Slotter is a unique two-player puzzle and strategy game. Each player starts with a set of numbered chips in two distinct colors. The objective is to guide your chips to the final row in the correct numerical order by rotating slotted wheels. Sounds simple? Here’s the twist: • The wheels come in different sizes and have varying numbers of slots. • You can only see your own side of the board. • Every move you make also affects your opponent’s wheels and chips — but you can’t see how. You win if: • You're the first to bring all your chips to the final row in the correct order, or • Your opponent accidentally places a chip in the final row with the wrong number. Game Modes: • Single player vs. computer • Two players on the same screen • Two players via local Wi-Fi • Two players via Bluetooth • Two players online via Game Center Game Settings: • Choose the number of chips • Define the target chip order • Decide who moves first • Customize your chip colors For Beginners: Want to learn faster? Here’s a little secret: In single player mode, press the wheel digits 3 – 4 – 5 – 2 – 1 to reveal your opponent’s chips. Great for practice!
