Interface
Semantic HTML + responsive CSS
Clear structure, large touch targets, visible focus and layouts that adapt from desktop to a 320-pixel phone.
Technology, made approachable
Built light. Made easy to use.
ACCU.eco uses straightforward web technology so seven energy games can load quickly, work on common phones and remain understandable without an account or complicated setup.
- Seven playable browser games
- No account required
- Phone-first controls
- No app-level ads or analytics
The practical foundation
Use familiar web tools. Keep the experience dependable.
The public games are deliberately built without a heavy front-end framework, external font service or runtime data feed. Fewer moving parts means faster loading and fewer ways for a player to get stuck.
Interaction
Vanilla JavaScript
Deterministic game rules, keyboard support, local progress and accessible feedback without a framework layer.
Page delivery
PHP 8.2 templates
Clean routes and shared header, footer and metadata components keep the public site consistent.
Progress
Local browser storage
Best scores and preferences stay on the player’s device. The current games do not require an account.
One dependable shell
Seven different games. The same promises underneath.
Phantom Shift, EcoShift, Grid Guardian, Watt Detective, Solar City, Charge Smart and Retrofit Rally use different mechanics, but each inherits the same expectations for readable controls, phone-first layouts, local progress and honest simulated outcomes.
Access
Touch, mouse and keyboard routes with visible focus and reduced-motion support.
Clarity
Plain-language choices, explicit selected states and results that explain what changed.
Privacy
No account is needed, and current game progress stays in the local browser.
Honesty
Game values are clearly presented as simulated learning outputs, not real utility or engineering results.
