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!

ReceptionRating · Positive reviews · Number of ratings

Memory Stamps holds the better App Store score, 4.3 against 3.0. That said, the two scores are not equally well evidenced: Memory Stamps has 82 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 74% of Slotter's written reviews are positive against 40% of Memory Stamps's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Slotter ships an update every 5 months, Memory Stamps fortnightly. The most recent releases landed on October 26, 2026 and October 25, 2026 respectively.
