You are currently playing version .


Level and Experience

The aim of the game is to increase your level. At the top of the screen you will see your level and the EXP needed to reach the next level. Interacting with the gameplay features you unlock will lead to ways to gain more EXP.

As your level goes up, parts of each gameplay feature will become more powerful. Progress in each feature so you can gain EXP and improve your level, which will in turn have an impact on all features.


Coins

At the top of your screen you will find 3 types of coins:

  • Yellow coins: A common currency you can earn in each feature.
  • Blue coins: A rarer currency that you only earn in features by performing more difficult tasks.
  • Green coins: These coins can only be earned by levelling up. When you level up you earn a number of green coins equal to the level you just completed, e.g. when levelling up from level 4 to level 5, you earn 4 green coins.

Coins are spent in Cool-Mart to unlock and upgrade game features!


Cauldron

Level bonus: Each scepter's base magic gain is equal to your level.

Gain magic over time. Spend the magic on items that produce more magic over time, or on powerful spells that can also improve things in other features.


Kingdom

Level bonus: All resource gain except EXP and coins is multiplied by your level.

Build and place buildings which produce resources every second. Use these resources to build more buildings, or unlock upgrades. The output of buildings can often be improved by building them on, or next to, various terrain features or other buildings. The resources produced by buildings can also include EXP and coins.


Dungeon

Level bonus: Each level increases your starting HP by 50.

Equip adventurers to explore dungeons. Kill monsters to gain yellow coins and EXP. Collect keys to open gates. Bump into things to interact with them or fight. You can move by either clicking on the buttons, or by moving with the arrow keys, WASD, or 8462 on the numpad.

Inside a dungeon instance, everything is temporary and will reset when you leave, with one exception, treasure chests. Treasure chests contain rewards that exist outside the dungeon instance, from equipment to equip for future dungeon explorations, to whole new dungeons to explore. Each treasure chest can only be opened once, ever.

Display large numbers with scientific notation instead of prefixes.

Show Kingdom resource incomes multiplied by your level instead of base values (turning this off does not impact the resources earned, only how it is displayed).
