Which browser games actually work on a phone

Most game catalogues carry a boolean from the supplier — mobileReady, availableOnDevice, or similar. It is tempting to print it and move on.

We checked it against the games’ own control text and it contradicted itself. In one batch we looked at, the supplier flag claimed phone support for 12 of 14 games whose own controls named a keyboard only. A game cannot simultaneously require WASD and run on a touchscreen with no keyboard.

So we use a rule that costs us reach and gains us accuracy: trust a “no”, never trust a “yes”. If the studio’s own control list names touch, tap, swipe or an on-screen joystick, we say it works on a phone. If it names only keys, we say reach for a computer. If it says nothing, we say we do not know — and every game page on this site prints that admission out loud.

They are not spread evenly. Some categories are almost entirely touch-documented; others lean hard on a keyboard.

Puzzle is the safest bet on a phone — 15 games with documented touch input, and the genre rarely needs precise timing. 2 Player is the worst, for an obvious reason: most of those games expect two people sharing one keyboard, which a phone does not have.

All of these name touch input in their own control lists.

• Puzzle — Hidden Object: Clues and Mysteries by DRA, and Good Sort Master: Triple Match by Sergey Tikhonov. Point-and-tap, no timing pressure.
• Sports — Basketball Stars and Golf Orbit. Short sessions, built for a thumb.
• Shooting — Bubble Shooter: Tap & Pop. Aim-and-tap rather than aim-and-strafe.
• .io — Snake 2048. One finger, one direction at a time.
• For Girls — Piece of Cake: Merge & Bake by Bravestars.

Every game page on SlowDen carries its own device line, taken from the same control list this article was built from. If the two ever disagree, the game page is the one to believe — it is generated from the registry directly.

Two things are true of every browser game on a phone, and neither is anyone’s fault:

• Small screens punish small targets. A game designed at 1920×1080 and scaled to a 390px-wide phone will have buttons near the limit of what a thumb can hit. Landscape helps more than people expect.
• Nothing saves. Browser games on SlowDen keep no account and no server-side progress, so closing the tab ends the run. On a phone, where the browser can discard a background tab to free memory, that matters more than on a computer. Finish the level before you switch apps.

There is no download and no install for any of them, which is the half we can actually promise. Whether your network lets slowden.com through is the other half, and we cover that in what “unblocked” really means.

The single most useful thing you can ship with a game is an honest control list. Thirty-nine of the games we host publish none, which means we cannot tell a player on a phone whether it is worth their time — so a lot of them will not click.

Name the inputs. Say “WASD or arrow keys” or “tap and drag”. It takes one line and it is the difference between a page that converts and a page that hedges. If you have a finished browser game, you can submit it to SlowDen free — any engine, any skill level.
