Playable with one thumb

Playable with one thumb

Most lists of phone games are lists of games that run on a phone. This is a list of games a single thumb can finish while your other hand is holding a rail, a cup or a shopping bag. That is a much narrower claim, and it is one you can check on us in about five seconds per game.

The two-corner test

Open the game and look at the bottom two corners of the screen. If there is a control in each of them, the game expects two thumbs, no matter what the store page says. That single test is what decides membership here, because no field in any catalogue records how a game is controlled.

We ran it on every candidate and it removed two of them. Super Cowboy Run puts an arrow in the bottom-left and another in the bottom-right; Viking Escape goes further with five buttons spread across both corners for aiming, jumping and attacking. Both are decent games and neither belongs in a set that promises one thumb. Smiles took one of the empty places: taps only, nothing else on the screen.

The rest of the rule is short — no rotating the phone, and a new round within one tap of the last one ending.

Ends without warning

Splishy Fish is the extreme case. Pixel-art coral pillars leave a gap for an orange fish and the gap is the whole game; half a second of hesitation puts you into a pillar and a GAME OVER banner across the middle of the screen. One tap starts the next attempt.

Flappy Ball is the same shape of problem wearing football boots: green pipes, a black-and-white ball, a circular PLAY button and a speaker icon on the opening screen.

Flappy Bounce belongs to that family by name. In the interest of not pretending, our test machine would not render its canvas, so we have nothing observed to tell you about it yet and will fill that in when its own page is written.

Ends with about a second of warning

Crazy Runner puts a seafront road behind two electricity pylons, coins strung in arcs with a +10 popping off each one, a clock and a distance counter in metres along the top, and a red pickup truck permanently behind you. The run we captured ended with the runner face-down on the tarmac six seconds in.

Ninja Run New moves the same idea to a palm-covered island in turquoise water, with three ninja portraits for lives, a trophy counter in metres, and coins with a crown stamped inside them. Its one control is an up-down triangle button in the top right corner, which is an unusual place to put it — but it is still one button.

Mad Fish swims a reef of purple coral, green kelp, a snail, a starfish and a treasure chest spilling blue gems, with two fish counters and a red clock ticking along the top bar.

Ends when you decide

Touch Ball opens on a circular PLAY button under seven-colour spotlights, with a MUSIC toggle and a High Score of zero beside it — a screen with nothing on it that a thumb cannot reach.

Stack Jump and Stick Panda are timing games rather than reflex games; Stick Panda sets its big blue play button against snow-covered mountains with HIGH SCORE printed underneath.

Smiles floats coloured smiley faces up through a brown cave for you to pop, and prints the scoring table permanently along the bottom edge: orange is worth 1, green 0, yellow 1, blue 1, purple 0, with three red faces set apart at the end of the row. Nothing to memorise.

Fishing Frenzy starts from a loading bar that fills to 100% and a round play button, then opens on blue water with fish of several sizes crossing it.

On a moving bus

Prefer the third group when the vehicle is moving. A screen that scrolls constantly while the bus sways is the combination that makes people feel ill, and the timing games hold their scene still. Rounds here are short enough that stopping after two of them costs nothing at all — there is no progress on this site to protect.

Three things people ask on the bus

How many titles survived the two-corner test?

Eleven. That number changed during the writing of this page: two titles failed the two-corner test and left, one arrived to replace them.

Do I have to rotate the screen?

Not for any of them. Several are built upright to begin with, and the ones drawn wide still play without turning the phone.

Does it work on a desktop?

Yes — we opened every one of them in a desktop browser and a mouse click does what a tap does. We have not tested keyboard keys game by game, so we are not going to claim those work. If you want short rounds without the one-thumb restriction, the three-minute set is the wider version of this idea.
