Every expedition begins with a single card and a simple choice: take the crystals in front of you, or reveal one more. The longer you stay in the mine, the richer the haul can become, but two Danger icons in the same position trigger a Cave-In and wipe out the entire Exploration Line.

The other awawas are part of the risk. They can steal cards, stop your turn, or make the next Danger icon disastrous, while Defense cards let you block an attack or turn it back on its owner. Build valuable columns, protect the one your rivals want most, and complete sets of four identical crystals to finish with the highest-scoring collection.

You always know what you stand to lose. Stop with a useful haul, or reveal another card and risk a Cave-In that clears the entire Exploration Line.

Everyone Stays Involved
 Non-active players can use Attack cards during an exploration, so nobody has to wait quietly for their next turn. Every valuable reveal gives the rest of the table a reason to interfere.

Attacks Have Answers
 Steal cards, force an early stop, or make the next Danger icon trigger a Cave-In. Defense cards can cancel those attacks, counter specific tricks, and sometimes punish the player who started them.

Quick Game, Sharp Decisions
 A game takes around 25 minutes, but your priorities keep changing. Chase higher values, complete identical sets, or spend a turn protecting the column everyone is watching. 

Start your expedition by revealing the top card of the Mine deck and adding it to the Exploration Line. Every crystal you uncover makes the trip more rewarding—and makes walking away a little harder. 
 
Some Mine cards let you hire an Assistant. Discard the card, shout “AWAWAH!”, and draw a new trick that may help your next expedition or disrupt another miner’s plans.

After every card, choose whether to stop and add the entire Exploration Line to your collection, or stay underground and reveal one more. A longer expedition can bring home a much better haul, but nothing is yours until you decide to leave.

Watch the Danger icons along the edges of the cards. When two appear in the same position, the mine collapses, the whole Exploration Line is discarded, and your promising expedition ends with nothing.

Your rivals do not have to sit quietly while you explore. They can steal a valuable card, force you to stop before you are ready, or add a nasty surprise that makes the next Danger icon much more threatening.

Fortunately, you are not helpless. Defense cards can cancel an attack, counter a specific trick, or even turn the situation against the player who targeted you. Around this table, a perfect sabotage can become a perfect mistake.

Instead of beginning another expedition, you may spend your turn placing one complete crystal column beneath your Safe. It is a slower move, but it keeps an important part of your collection beyond the reach of your rivals.

When the Mine deck runs out, every crystal counts, whether it was protected or left in your collection. Add their printed values and earn 5 extra points for every set of four crystals with the same color and value.
