Single-Jack Fever

The mine shafts are officially open!

Introducing Single-Jack Fever, an all-new, limited-time excavation event that challenges Commanders to smash through 100 floors of rock and uncover massive Premium Rewards. Grab your Single-Jack hammer and start swinging: every floor holds a hidden grand prize, and the deeper you dig, the richer the haul.

The event is split into two main screens: Excavate (where you break stones to find rewards) and Tasks (where you complete missions to earn more Single-Jacks).

Excavate: Strike your Premium rewards!

All of your mining takes place on the Excavate tab. 

The event spans 100 progressive floors, and here is how a standard floor flows:

Step 1: Pick Your Premium Reward - Before digging, select your Premium Reward from 5 high-value options. It will be hidden under one of the 25 stones on your current floor. You can change your choice at any time before you actually strike it.

Step 2: Break the Stones - Spend 1 Single-Jack to break a stone.

• Standard Rewards: Most stones hide consumable items that go straight to your inventory.
• The Premium Reward: Finding your selected grand prize gives you a choice: keep spending Single-Jacks to break the remaining stones on your current floor, or head straight down to the next level.

Step 3: Advance and Earn Milestones - Every floor you clear (by finding the Premium Reward and descending) earns 1 Milestone Point. Collect these points via the Milestone Chest icon on the Excavate tab: the deeper you dig, the richer the rewards!

Floor Types & The Dig Limit

To ensure you never get stuck on a board with bad luck, the event features a strict Dig Limit. If you reach the limit without finding your chosen reward, your final allowed dig is guaranteed to uncover it, and you will descend to the next floor automatically.

• Rock Levels: Standard floors. The Dig Limit triggers on your 14th stone.

• Rich Vein Levels (Every 5th Floor): These feature golden stones and richer standard rewards. The Dig Limit triggers on your 22nd stone.

Lucky Strikes Log

Watch the announcement bar on the Excavate screen to view the Lucky Strikes record. Tap on it to check out live log of the latest 30 miners who successfully struck their Premium Reward!

(Players who only find their reward via the guaranteed Dig Limit are not listed here).

Tasks: Earn extra Single-Jacks!

To break stones, you need Single-Jacks. The Tasks tab is your central hub for acquiring them to continue your excavation.

• The Welcome Gift: Claim 3 Free Single-Jacks right at the top of the Tasks tab at the start of the event. (Note: This is a one-time gift, not a recurring daily reset!)
• Event Tasks: The main feature of this tab is a list of specific in-game missions that reset daily. By completing these activities, you earn additional Single-Jacks needed for your excavation!

The Store:

If you clear all your tasks and still want to dig deeper, tap the "+" icon next to your Single-Jack balance to visit the Store and purchase event-exclusive deals in the Single-Jack Stash tab.

Intel

• Task Resets: The free missions on the Tasks tab reset every day at 00:00 UTC. You must claim your earned Single-Jacks before this timer expires; you cannot claim completed tasks from yesterday!
• Leftover Single-Jacks: When the 5-day event ends, any unspent Single-Jacks in your inventory will be automatically exchanged for resources.

PRO TIP: Strategic Advancing - If you find your Premium Reward on your very first few swings, it is usually best to head straight down to the next floor immediately rather than spending more Single-Jacks to uncover standard resources. Descending faster means more Milestone Points and more Premium Rewards!
