Getting started
There is no install step, so this is shorter than it looks. It is mostly about what happens after you press play — where your scores go, and what to do on the rare occasion nothing appears.
What you need
A browser released in the last few years, and that is genuinely the list. Chrome, Safari, Firefox and Edge are all fine, on phones, tablets, laptops and desktops alike. You do not need an account, an app store, a plug-in, or a particularly fast connection once the game has loaded.
- Install
- None. The URL is the game
- Account
- None, for any game
- Input
- Touch or mouse
- Offline
- No — the first load needs a connection
- Cost
- Free in the browser; apps may offer optional purchases
Phone or desktop
Every game is built around a single pointer, so a thumb is a first-class input rather than a compromise. On a phone, portrait is the orientation the games are laid out for. Break Works needs it: on a phone of ordinary proportions held sideways it cannot really be played, so turn the device upright before starting a stage.
On a desktop the main advantage is precision. Block Pong is easier to aim with a mouse than a thumb, and so is a wrecking ball.
Where your progress lives
On your device. Best distances, best scores and the difficulty tier you last played are written to your browser's own local storage, and that is the only copy.
There are three practical consequences worth knowing before you set a record:
- Records do not travel. A best set on your phone is not on your laptop. Nothing is syncing, because nothing knows who you are.
- Clearing site data clears them. "Clear browsing data" with site data ticked will take your scores with it, and there is no backup to restore from.
- Private windows forget. A private or incognito window usually discards local storage when it closes, so a run set there will not be there tomorrow.
Iromino saves your progress and unfinished puzzles on your device. If your browser blocks site storage, the game cannot start. Allow site storage for the game's address before trying again.
Because that means accounts, and accounts mean holding personal data on people who only wanted to knock a stack of crates over. Keeping scores on the device is the version of this trade-off we prefer. What we do collect is set out in the プライバシーポリシー.
Data and battery
The first load downloads the game's files; your browser can cache many of them for later visits. Download size and graphics demands vary by game. Animation uses more battery than reading a static page, so long sessions can run down a phone. Browser games wait for an interaction before starting audio.
When a game will not start
Rare, but the causes are usually one of these, in the order worth trying:
- Reload the page. A partial first load — a dropped connection halfway through — accounts for most black screens.
- Check hardware acceleration. Games that use WebGL need it. If it is disabled in your browser's settings, or the browser has fallen back to software rendering, the game will either refuse to start or run very slowly.
- Try without extensions. Aggressive content blockers and script blockers occasionally take out the game bundle along with everything else. A private window is the fastest way to test that theory.
- Close some tabs. On phones especially, a 3D game asking for memory that is not there is quietly reloaded by the operating system.
- Tell us. If none of that helps, Support explains what to include so the problem is reproducible.
