A mini game teaches itself in one round

A cut-down version of a big game is still a big game. It opens with a tutorial, hands you a currency you have not earned yet, and assumes you will come back tomorrow to finish what you started. Miss a week and you return to a save file you no longer understand. A real mini game carries none of that. Snake has one rule: eat, grow, do not hit a wall. You know it in four seconds.

The test is what happens when a round ends. A mini game gives you a number and a clean board. Nothing is pending. You can put the phone down with nothing hanging over you, or start again, which costs you nothing but the round itself. That ending is the whole design. Games built to keep you are built to leave a thread dangling. Games built for a short session tie it off every time.

Open a folder of games with five minutes to spare and you will spend one of them deciding. You read a tile, remember you were bad at that one, back out, scroll, open another. The menu is a small tax you pay before any fun starts. Reel Games removes the decision. Games launch instantly, with no loading screen between one game and the next. If the game in front of you is not the one you want, swipe up.

Swiping back down returns you to the game you were on, so the feed is not a one-way conveyor. The other thing a feed does is put games in front of you that you would never have picked. Nobody browsing a menu goes looking for Tower of Hanoi. It shows up anyway, you move three discs to see how it works, and you are still moving discs a while later. A menu only hands back what you already knew you liked.

Mini games get filed under arcade because arcade is where the format started. The range is wider than that. Puzzle games like Sudoku and Minesweeper are solved rather than survived, and they sit still while you think. Word games like Connections and Anagram are five minutes of vocabulary and nothing else. Strategy games like Chess and Checkers are the outlier: turn-based instead of timed, and the round runs as long as you let it.

Skill games are the third shape: Darts, Bowling, Pool, Cup Pong. Aim, release, watch, repeat, with no rules to remember between throws. The library runs to 47 games in a 50.7 MB download, and new games are added regularly. All of it sits on the phone, so a dead signal does not end a round. Scores sync to global leaderboards when you are back online, which gives a two minute game something to add up to.
