Currencies

There are 4 currencies in the game. Players can see how much of those they have by checking the top right of their screen. The general purpose of these recource is to exchange them for various things.

Nymph Coins
Player cannot store more coins than their treasuries allow. Any amount of coin which exceeds the treasury capacity will be placed on the map. You cannot merge or combine excess money. And you cannot activate/consume coin items, when storage is full. Players can see the exact storage amount offered by their treasuries by clicking the coin bar at top right. Coins can be used for purchasing the following in the shop:

 * If you try to clean home area by selling, each sold item will drop its own excess money, should you be coin capped
 * Player should not be coin capped before going into new stages. Some stages have quests that requires collecting coin items.
 * It is advised to collect the highest Jewelry Items and merge lower Tier items up first
 * Highest tier treasury building does not drop Jewelry.

Crystal Bricks
Crystal Bricks are the main currency for the building tab in the shop. Players cannot store more than their warehouses allow. Any amount of Crystal Bricks which exceeds the warehouse capacity will be placed on the map as an unmergable pile. The Player can see the exact storage amount offered by their warehouses by clicking the crystal bar at top right. Crystal Bricks can be used for purchasing the following in the shop:

 * Opening Safes.

Additional notes:


 * Player should not be capped before going into new stages. Some stages have quests that requires collecting crystals.

Crowns
To play maps, you need Crowns. Consider them a time currency. You regenerate 1 Crown per hour up to 7. You can have more Crowns temporarily, by activating a Crown or Diadem.

You get crowns and mostly coronets from


 * Level Rewards
 * Opening Pods
 * Harvesting the top Crystal Mine
 * Spending Rubies directly on the Crownometer

Rubies
Rubies are the "hard currency" of Merge Nymphs. Players start with 30. Ruby "storage" automatically expands to the highest amount the player has ever reached. Always try to merge 5 rubies at a time to make the most of it (12.5 rubies give 30 if perfectly merge).

Rubies can be obtained from the following sources:


 * They can be purchased for Nutaku gold in the shop. That gives the currency Rubies, not the item Rubies.
 * Bundles and special offers (purchasable with Nutaku Gold)
 * Quests can have rubies as a reward.
 * Some Stages contain rubies.
 * Stage 40 - National Treasury: The rubie can be bought after the finish, making it a good repeat stage for harvesting rubies
 * Most Stages can award rubies (about 1% chance per free reward) (the stages that can't give rubies will usually award coronets/crowns at 1% chance instead)
 * Pods can contain rubies.
 * Safes can contain rubies (about 1 in 20-25 for low tiers, perhaps 1 in 10 for high tiers)
 * Events with event stages tend to have some rubies on the event stage

Players can spend rubies on the following:


 * To refill crowns, at 8 rubies per crown.
 * To buy various islands at home.
 * To open dimensional chests and gargoyles.
 * Extra time in challenges at 50 rubies per 30 seconds.
 * Taking items from levels home.
 * Buying certain items in the shop.
 * Unlocking more slots for vault safes.
 * Skipping vault safes, opening them right now.
 * Instantly recovering the stamina of sleeping nymphs (and recovering double too).
 * Opening event chests.

Spending advice
What to spend rubies on depends on the player's needs. There are few things that are not obtainable without rubies. And even rubies can be farmed, when spending enough time. Everything that can easily be obtained by harvesting, like Crystals or Eco-Dildos, are rather bad spending options. The harvestable objects are a better choice, but low Tiers are easy to make and high tiers are expensive.

Of special interest are some alchemist offers, since they are on discount. Event maps have their own shop and usually offer shortcut items or items to correct mistakes you made. On home camp you can get the islands for more space and some goodies.

All in all it boils down to time and your Ruby purchases should save you time or give you stuff not related to time. As events are time constrained, you might want to save some Rubies for those.

For players who would like to spend nutaku gold, there are often special offers giving discounts and items you might have missed from events.
