Easy to start, easy to stop
Five Dice Scorecard is a solo dice game where you roll five dice up to three times a turn and fill one of 15 boxes, using the Nordic rule set with pairs and exact straights. Pegball points a cannon down a tall board of pegs, and your goal is to clear all 14 orange pegs before you run out of balls. Marble Spiral sends a chain of marbles along a winding groove toward a hole, and you fire marbles into it to match three of a color.
Typer Defense is pure reflex. Single letters fly in from both sides, and you press the matching key before one reaches the circle in the middle. Speed matters more than spelling here, since each target is just one letter.
Math Sprint Game and Factors Game give your mental math a workout without much pressure, and both play well on a phone.
Slow-burn idle games
Progress Knight follows one life in a medieval kingdom, starting as a penniless 14-year-old beggar. Work and skills tick along by themselves, and when you grow old an amulet lets you begin again with lasting bonuses. Realm of Ages Clicker and Prestige Tree Rewritten scratch the same itch of numbers that keep climbing. They suit a tab you check on now and then rather than a game you stare at.
Little toys and odd ideas
Unicorns Off My Lawn casts you as a leprechaun protecting rainbow flowers from a herd of clumsy unicorns. Factors Game is a number puzzle where you drop through rows of tiles, dividing as you go, to land on exactly 1. Tiny Synth Piano is not really a game at all, just 36 keys you can play straight away. Its three rows each cover one octave, and every note is made live by the browser.
Pixel Sketch Studio is another toy rather than a challenge, a place to doodle when you do not feel like keeping score.
