What a Shakes & Fidget bot is
A Shakes & Fidget bot (often shortened to SF bot or S&F bot) is a program that plays the idle RPG Shakes & Fidget for you. It runs the repetitive daily tasks on its own, so your character keeps progressing without you clicking through every menu.
That is the whole idea. Shakes & Fidget is a good game with a lot of chores in it, and the chores are identical every day.
What a bot typically automates
| Area | What it does |
|---|---|
| Quests | Accepting quests, buying beer, running the thirst for adventure loop |
| Arena | Daily arena fights and climbing the ranking |
| Scrapbook | Targeting the players holding items you are still missing |
| Dungeons | Light and shadow dungeons, the Twister and the Tower |
| Fortress | Gathering wood, stone and silver, and queuing upgrades |
| Underworld | Collecting souls and silver, and upgrading buildings |
| Pets | Feeding, pet dungeons and pet arena |
| Guild | Portal, hydra, raids, attack and defence |
| Tavern | Calendar, wheel of fortune, dice game and the toilet |
| Timed events | World Boss, Hellevator and the Legendary Dungeon |
The last row is the one most bots leave out, and it is the row that costs the most clicks to play by hand. Mercy SF covers it, and the pages are under the big events.
Two very different kinds of tool
People use "bot" for both of these, and they are not remotely the same thing.
1. Client modification and macros. Some tools inject code into the game client, or replay mouse clicks on screen. These are fragile, they break on every game update, and they are what most people mean when they say "Shakes and Fidget mod".
2. API automation. Other tools talk to the same official Shakes & Fidget servers your browser already talks to, sending the same requests the game itself sends. Nothing is injected and nothing is patched.
Mercy SF uses the second approach. It is a standalone application, not a mod. It logs in through the official single sign-on and drives your account through the game's own interface. Your credentials are stored locally and encrypted, and there is no account server holding them.
Is it safe?
Two separate questions, and they deserve separate answers.
Is the software safe? It runs entirely on your machine. Your credentials are stored locally and encrypted, and no account server holds them. Nothing about how you play is collected or sold: no account names, no characters, no progress, nothing out of the game state.
There is no code signing certificate, so Windows warns about an unknown publisher every time. That warning means the publisher is unverified, not that something was found in the file. The check you can run yourself is the published SHA-256 checksum.
Is automating an account safe? That is a different question, and the honest answer is that automation can be against the game's terms of service. The consequence of a breach, whether a warning, a suspension or the loss of a character built over years, falls on you and on nobody else. Read the game's own terms and decide for yourself.
That risk is why Mercy SF is deliberately conservative about how fast it acts, and why the crawler has a per-minute rate limit rather than only a per-cycle one.
What makes one bot different from another
Three things, in practice.
Whether it tells you what it is doing. A bot that says "waiting" is very hard to trust. Mercy SF names the opponent it will fight next and the reason it picked them, and when it does nothing it says why.
What it costs to run. Mercy SF is built with Rust and Tauri 2 and uses the operating system's own WebView. There is no bundled Chromium and no Node runtime in the background. About 200 MB per running character.
What it costs. Every module is unlocked for everyone. No licence key, no supporter tier that gets the good features, no trial.
Try it
The install and first run guide covers downloading, signing in, choosing which modules to run and starting the bot. It takes about a minute.
