Every draw is a gamble

• Spend coins to draw a random tower.
  
• Merge two towers of the same era and type — what comes out is a random tower of the NEXT era. The draw is random, and so is the merge.
  
• Climb from stone-age spearmen to laser turrets across 5 eras and 20 tower types.

Turn bad luck around

• Enemies keep circling the board. Let them pile up and it's over — but one lucky high-era tower can wipe the field clean.
  
• Boss rewards: pick one of three to patch your run's weakness.
  
• Missions give surplus low-era towers a second purpose. No dead draws.

Defend the table together

• Up to 4 players, each holding a seat at the table. If one seat falls, the table falls.
  
• Reinforce a friend's lane and keep the weakest board alive.

An arcade, not a history lesson
