For logic and deduction, Sudoku and Minesweeper are the two that reward patient reasoning rather than speed. For memory, Number Memory tests digit span and Simon Says tests sequence recall, while Memory Match works spatial memory instead.

For words, Wordle and Hangman test vocabulary and Anagram and Word Search work on spelling. For arithmetic, Number Pop and Whack-a-Mole drill addition under time pressure. For reflexes, Reaction Time and Color Match measure attention rather than knowledge — and Color Match in particular is far harder than it looks.

Tic-Tac-Toe, Connect Four, Checkers and Dots & Boxes all support pass-and-play on a single device, so two people can share one phone without anybody needing an account.

Each also has a computer opponent of a different strength. The Connect Four CPU searches five moves ahead and is genuinely hard; the Tic-Tac-Toe one follows a simple priority list and can be beaten with a fork. If you want a game you can actually win, start there.

Tap the star on any card to pin a game to the top of this page, which is worth doing if you play the same two or three regularly. Games with difficulty levels keep a separate leaderboard for each, so an Easy time never competes against a Hard one.

Scores save locally without an account. Registering keeps them on the server instead, so they survive a cleared cache and follow you between your phone and a laptop.

Everything here is short enough to finish in a break and quiet enough for a classroom. There is nothing to install, no in-game purchases, no chat, and no way for one player to contact another — which matters when the people playing are children.

For daily practice rather than free play, the Congak challenge at cerdikcerdik.com/math and the Daily Quiz at cerdikcerdik.com/quiz both run once a day and keep their own streaks.
