Frequently Asked Questions
Do these games work offline — can I play without an internet connection?
Yes — after the first visit, all ToolStand games work offline. Minesweeper and Snake Game have no network dependency at all (pure client-side logic). The Wordle Solver has its word list embedded in the page. Disconnect and play anywhere — the service worker cache keeps all assets available.
Are high scores saved — will I lose progress if I close the tab?
All games use localStorage for persistence: Minesweeper saves your theme preference (light/dark mode), Snake Game stores your high score, and Reaction Time Test keeps your best average time across sessions. This data stays in your browser — it's never sent anywhere. Clearing browser data resets all scores.
Can I play on mobile — do the games work with touch screens?
Yes — all games are fully responsive and touch-compatible. Minesweeper supports tap-to-reveal and long-press-to-flag. Snake Game includes on-screen directional controls for touch devices (in addition to keyboard arrows on desktop). The grid sizes scale to fit any screen width. Tested on iOS Safari and Android Chrome.
Metronome — how precise is the timing and can it handle odd time signatures?
The Metronome uses the Web Audio API's precise scheduling clock (not setTimeout/setInterval, which drift), delivering sample-accurate timing for BPMs from 20 to 240. It provides a visual pulse indicator alongside the audio click. The tool does not enforce time signatures — it produces a steady beat at the selected tempo, which works for any time signature (you accent the downbeat yourself). Pair it with the BPM Tap Tempo to find the tempo of an existing recording by tapping along.
