The Crusher Truck mini-game is a fast-paced bonus stage that automatically triggers when you move between mines in the main game, as well as in weeklong event mines. You have exactly 30 seconds to steer a powerful machine, smash through rows of obstacles, and grab as many rewards as possible!
Rocks and Objects Guide
Different objects on the track yield different rewards. Target high-value obstacles to maximize your score, as rewards automatically scale higher as you progress further in the main game.
| Rock Type | Reward / Effect | Notes |
| Basic Rock | Small amounts of Elixir and Cards | The most common obstacle in the field. |
| Soft Currency Rock | Elixir | Spawns in small and large variants. |
| Hard Currency Rock | Gems | ⚠️ Spawns only in the main mine. |
| Chests | Elixir and Cards | Drops vary by rarity (Wooden, Iron, Forged, Silver). |
| Leaderboard Rock | Crowns | ⚠️ Spawns only during weeklong events. |
| Boundary Rock | Minimal rewards | Dark, extremely tough rocks that mark the edge of the screen. Avoid them! |
Power-Ups and Boosts
Smashed power-up items activate instantly to help you clear the field faster:
Speed Boost: Temporarily increases your truck's driving speed.
+5 Seconds: Adds 5 precious seconds to your countdown timer.
Big Blast!: Triggers a massive explosion, instantly collecting everything in its radius.
Jumbo Crusher: Temporarily doubles the truck's physical size, allowing you to plough through multiple lanes at once.
Upgrading Your Truck with Epic Cards
You can permanently enhance your vehicle's stats in the main game by leveling up specific Epic Cards in your collection:
🏎️ Crusher Tuning (Speed)
Increases your truck's base speed. Starting at level 2, each upgrade also visually changes your truck's appearance. At the maximum level, your vehicle drives twice as fast as the baseline speed.
⚠️ Note: This card's effects apply only within the main mine campaign, not during special events.
💣 Bomb Launcher (Crusher)
Unlocks an automatic bomb-throwing mechanic. Upgrading this card reduces the cooldown delay between throws. At maximum level, the truck fires one bomb per second. Bomb explosions can also automatically trigger nearby power-ups!
⚠️ Note: This mechanic works only within the main mine campaign.
💡 Strategy Tips for Maximum Rewards
Ignore the Edges: Do not waste your limited 30 seconds trying to break dark Boundary Rocks. They take too long to destroy and offer almost nothing in return.
Chain Your Boosts: Prioritize grabbing every speed and time boost on your path to cover more distance and break more chests.
Level Up Epic Cards: Regularly invest in your truck-related Epic Cards to significantly increase your resource yields during transitions.
