About This Game

TOWER DEFENSE, DEALT FROM YOUR DECK

In Prismhold every tower is a card. Build a deck from 196 towers across 14 elements, then draft from it every wave: the shop deals five cards, you buy, unlock slots beside the path with gold, place your towers and hold the line against wave after wave of creatures. How far can you go?

MERGE THREE, EVOLVE WITHOUT LIMITS

  • Three identical towers merge into the next evolution: stronger, bigger and with a new look
  • There is no evolution cap. Keep merging: III, IV, V and beyond
  • A focused deck deals the same cards more often, so you evolve faster

14 ELEMENTS, 196 WAYS TO HIT

Fire, Water, Ice, Lightning, Darkness, Light, Poison, Nature, Earth, Air, Spirit, Cosmic, Laser and Firearms. Every tower attacks in its own way: dragon breath, chain lightning, black holes, falling stars, tornadoes and ricocheting diamond beams. Creatures resist some elements and break under others, so mix your deck.

BOSSES, FLYERS AND ELITES

  • Every 10th wave a crowned boss arrives with a shield, regeneration, fury or splitting
  • A boss that breaks through costs many lives, but brings extra gold when it falls
  • Flying waves only fall to towers with the wing mark
  • 200 creatures from 8 biomes, and every cycle brings tougher elite waves

PLAY TOGETHER

  • Together: two players defend one map with shared lives, each with their own gold and towers
  • Side by Side: up to 6 players, each on their own copy of the host's map. Click a player's card to watch their map, and outlast them
  • Join an open game from the lobby list, keep your lobby friends-only, or lock it with a 4-digit password

ENDLESS RUNS, REAL PROGRESSION

  • Unlock slots with gold and fill the whole map: no tower limit, 8 maps that unlock as you play, endless waves
  • Crystals grow steeply with the wave you reach, and beating your record pays a bonus
  • Open element packs with crystals, upgrade your cards up to ★10 and complete the collection
  • Augments change every run: economy, evolution and element mastery
  • A daily challenge with the same map, deck and seed for everyone, Steam leaderboards, daily quests and 47 achievements
  • Gifts during your first two hours, including a Legendary tower pick
  • Available in 23 languages
