Zen

The Zen Mode is an infinite play mode, play as long as you want.
The goal is simple: reach the metrics target to progress to the next round.

Rounds

Every round has a resource target. You advance to the next round once you reach the current resource target.
There is no time limit - take as long as you want/need.

Resources

Resource production works exactly the same as it does in Challenge Mode.

You can find basic information on how the tiles interact with one another to produce resources in the Tiles Overview

Hand & Redraw

The Card deck works exactly the same way as it does in Challenge Mode, but the deck is frequently refilled, so you don’t run out of cards to draw.

You still get free and paid redraws. Note that a paid redraw reduces your current resources, thus setting your current round progress back by a bit.
