RENEWAL

Tap & Drop has been reborn as Chroma Crystal. Available now on the App Store.

Chroma Crystal is a roguelite that combines deck building with bouncing balls.
Create mana with cards, then transform it with pins and pockets. Shape both your deck and the board as you set out on an 18-round journey through the forest edge, the cave, and the ruins.

Gameplay

Battle screen: Jis and Basil face two bees in the forest
Battle

Battles where cards and board connect

Cast spells to create balls of mana and summon pins with supports. Each pin hit builds points and combos, and the pocket a ball lands in turns it into attack or defense. Mix Quick, Enchant, and Magic Circle cards to find your own way to fight.

A shop that grows your deck and your board

Between battles, visit the shop of Lilica, the demon shopkeeper. Collect cards, relics, and potions, and place special pins wherever you like. Customize the board itself with gadgets like cannons and splitters, and by modifying the pockets.

From the forest to the ruins, 18 rounds

Journey with the hero Jis from the forest edge through the cave and on to the ruins. Build your deck and board anew on every run as you aim to conquer all three areas.

Small choices, big chain reactions

Where you drop the mana, where you place pins, the order you play your cards. A perfectly aimed bounce or an unexpected chain can turn the tide of battle.

Forks in the road and journey events

Along the way, the path splits. Choose your own route: a regular battle, an elite battle, or an event. On the road you'll come across events with their own illustrations, and earning achievements unlocks new cards.
