+# Escape from Jail — Design Spec
+
+**Date:** 2026-06-28  
+**Status:** Approved
+
+---
+
+## Overview
+
+Add a **Bust Out** mechanic to the jail page. A jailed character can spend cash to attempt an escape. Success rate is based on `dexterity + speed` stats. Success releases immediately; failure multiplies remaining sentence by 1.5×. Cash is always deducted regardless of outcome.
+
+---
+
+## Data Model
+
+No new tables or columns required. Uses existing `characters.status` and `characters.in_jail_until`.
+
+---
+
+## Bust-Out Mechanics
+
+### Cost
+1000 cash (from `config('game.jail.breakout_cost')`). Deducted whether the attempt succeeds or fails.
+
+### Success Rate Formula
+```
+success_rate = min(
+    config('game.jail.bust_out_max_chance'),
+    config('game.jail.breakout_chance') + (dexterity + speed) * config('game.jail.bust_out_stat_multiplier')
+)
+```
+
+With defaults:
+- `breakout_chance` = 0.05 (existing)
+- `bust_out_stat_multiplier` = 0.003 (new)
+- `bust_out_max_chance` = 0.80 (new)
+
+A fresh character (dex=5, speed=5) starts at **8%**. A well-trained character (dex=50, speed=50) reaches **35%**. Max possible is **80%**.
+
+### On Success
+- Deduct `breakout_cost` cash
+- Set `status → active`
+- Set `in_jail_until → null`
+- Redirect to `game.dashboard` with success flash
+
+### On Failure
+- Deduct `breakout_cost` cash
+- Multiply remaining jail time by `sentence_multiplier` (1.5×):
+  `in_jail_until = now()->addSeconds(ceil($character->in_jail_until->diffInSeconds(now()) * 1.5))`
+- Redirect back to `game.jail` with failure flash showing new release time
+
+---
+
+## Config Changes (`config/game.php`)
+
+Add two keys to the existing `jail` block:
+
+```php
+'jail' => [
+    'sentence_length'        => 3600,
+    'breakout_chance'        => 0.05,
+    'breakout_cost'          => 1000,
+    'sentence_multiplier'    => 1.5,
+    'bust_out_stat_multiplier' => 0.003,  // per combined dex+speed point
+    'bust_out_max_chance'    => 0.80,     // cap at 80%
+],
+```
+

+
+## New Files
+
+| File | Purpose |
+|------|---------|
+| `app/Services/Game/JailService.php` | `bustOut(Character): array`, `sendToJail(Character, int): void`, `releaseFromJail(Character): void` |
+| `app/Http/Controllers/Game/JailController.php` | `bustOut(Request): RedirectResponse` |
+
+### `JailService` interface
+
+```php
+/**
+ * @return array{success: bool, message: string}
+ */
+public function bustOut(Character $character): array
+
+public function sendToJail(Character $character, int $seconds): void
+
+public function releaseFromJail(Character $character): void
+```
+
+`bustOut()` returns `['success' => true/false, 'message' => string]`. The message is a human-readable outcome description suitable for a flash notice.
+
+---
+
+## Modified Files
+
+| File | Change |
+|------|--------|
+| `config/game.php` | Add `bust_out_stat_multiplier` and `bust_out_max_chance` to `jail` block |
+| `resources/views/game/jail.blade.php` | Add Bust Out card below status card |
+| `routes/game.php` | Add `POST /game/jail/bust-out` → `JailController@bustOut` |
+
+---
+
+## Routes
+
+```php
+Route::middleware(['auth'])->group(function () {
+    Route::post('/game/jail/bust-out', [JailController::class, 'bustOut'])->name('game.jail.bust-out');
+});
+```
+
+The bust-out route lives in the same `auth`-only group as the existing jail view route (no `verify.character` needed — jailed characters can't have characters, but do need auth).
+
+---
+
+## UI — Jail Page
+
+Dark crime theme, consistent with existing pages.
+
+**Bust Out card** sits below the existing status card. Contains:
+- Success percentage (calculated from character stats, shown as e.g. "12% chance")
+- Cash cost ("Costs $1,000")
+- "Bust Out" button — disabled with tooltip if character has < 1000 cash
+- CSRF-protected POST form
+
+**Flash messages:**
+- Success: "You escaped! You're free." → redirects to dashboard
+- Failure: "Bust failed — your sentence was extended to [new release time]." → stays on jail page
+
+---
+
+## Out of Scope (this iteration)
+
+- Busting out another player (requires PvP)
+- Nerve/energy cost for bust attempts
+- Per-attempt cooldown (failure penalty is time extension only)
+- Bust attempt history / activity log entry (can add later)
