The Sortuda

The Sortuda is the game's capsule machine. You spend a Token, the machine spins, and out comes a coloured capsule with a prize inside.

It is an honest gacha, and that means three concrete things:

the odds are published on the machine itself, not hidden;
the prize is already rolled when the capsule drops, and the colour that counts is the opened capsule. Sometimes it drops disguised one colour lower and cracks open into its real colour ("It cracked! It was better!"). The disguise only goes down: the scene never shows a better prize than the one you got. In a 10-spin it only shows up from red upwards (a silver can drop as red, a gold as silver);
the guarantee counter is never reset by anything except an actual gold capsule, and that includes a gold that dropped disguised as silver.

The five colours

Capsule	Chance per spin
Blue	60%
Purple	25%
Red	11%
Silver	3.4%
Gold	0.6%

Within each colour, the prize is rolled among that drawer's options, and each option's weight is published too. Prizes are pokemon and items. The Master Ball and the special shiny are small slices inside the gold drawer, and they only come from a spin: no trade on the machine hands those two over.

The gold guarantee

Spins without gold	What happens
1 to 55	The usual chance, 0.6%
56 onward	The gold chance rises 2 percentage points per spin
80	Gold guaranteed

The counter only resets when you pull a gold capsule. It does not reset by leaving the game, by the day changing or by buying Tokens.

In practice: by spin 79 the chance is already around 49%, and spin 80 closes the contract.

Spin 10

Spinning ten at once costs 10 Tokens and guarantees at least one red capsule or better in the batch: the worst result of the ten is upgraded to red. The guarantee only ever improves the batch, never worsens it.

Stardust

Every spin pays Stardust, on top of the prize. No capsule comes out empty.

Capsule	Stardust change
Blue	1
Purple	2
Red	5
Silver	12
Gold	30

A duplicate prize pays Stardust worth a whole Token, on top of the change.

And Stardust buys spins back:

40 Stardust = 1 Token.

The loop closes honestly: spinning makes Stardust, and Stardust eventually hands a spin back.

Getting Tokens without paying

Source	How much
Daily Token	1 a day, free, just log in and claim. A brand-new character gets the first one 1 hour after it is created
Surplus: evolution stones	8 identical stones = 1 Token
Surplus: fossils	3 identical fossils = 1 Token
Surplus: Elixirs	5 identical Elixirs = 1 Token
Stardust	40 = 1 Token

The surplus trade exists because idle stones are the game's biggest dead stock. If your bag holds thirty stones you will never use, they become spins.

The trade counts the same item: 8 Fire Stones make 1 Token, but 4 Fire Stones plus 4 Water Stones do not. Elixirs work the same way, same type and same duration: 5 EXP Elixirs (1h) become 1 Token, for any of the four types (EXP, Gold, Catch and Trainer) and any duration (1h, 3h or 8h). Once you have enough of one item, it shows up in the The machine eats surplus box on the Sortuda screen, with the button to trade.

Tokens are also sold in the VIP Shop, for Safira.
