Which A/B tests run in Butcher Hero: forge, shop layout, passes, enemy strength and rewards. Variants, who gets them and how to find your group.
For each test your group is picked at random from the rule's variants and saved in the game. A rule with “+” also applies to existing players without a group. Remote config data as of 2026-11-09.
Whether item sharpening opens in the forge and what its upgrades cost.
Who gets it: everyone without a group yet: A, B or C — equally.
How to find your group: Complete the blacksmith quest chain. Still no sharpening — group A. Forge upgrades cost gems and come as a list — B. Upgrades on a map for blacksmith elixir — C.
Whether the crystal pass is sold in the shop.
Who gets it: everyone without a group yet: B.
How to find your group: There's a crystal pass banner in the shop — group B.
Whether the shop has a “No ads” purchase (in the game: removes all ads, stat offers become free) and how often ads are shown.
Who gets it: new players only: B or D — equally.
How to find your group: Look for the “No ads” purchase in the shop. If it's there — group D, if not — B.
A section in the gem shop: “Complete tasks and get free gems” (Tapjoy service).
Who gets it: new players only: A, C or D — equally.
How to find your group: Open the gem tab in the shop. No tasks section — group A. There until island 10 — C, until island 6 — D.
A separate quest on the first island: the boss kidnaps Miss Butcher; you need to take the key from the guard, get stronger, beat the boss and free her.
Who gets it: new players only: A or B — equally.
How to find your group: If Miss Butcher appeared in a cage on the first island with the “Save Miss Butcher” quest — group B. If there was no such quest — A.
Which shop layout the game opens: the updated one or the old one.
Who gets it: new players only: A or B — equally.
How to find your group: Compare your shop with a friend's on the same game version. If the design and sections differ, you're in different groups.
Whether the soul pass is sold in the shop.
Who gets it: everyone without a group yet: B.
How to find your group: There's a soul pass banner in the shop — group B.
How much the stats from rewards and purchases are multiplied.
Who gets it: new players only: C or F — equally.
How to find your group: Not shown in the game. Indirectly — by comparing stat sizes in the same purchases with a friend on the same island.
Whether magic dust is returned when a crystal enchant fails, and how much.
Who gets it: everyone without a group yet: A, B or C — equally.
How to find your group: After a failed enchant check whether dust came back: no — A, a little — B, three times more — C.
The enemy strength multiplier on islands. It's what makes the game harder for some players than for others.
Who gets it: new players only: A or B — equally.
How to find your group: The game doesn't show the group directly. Compare enemies with a friend on the same island at similar hero strength: in group B enemies get noticeably tougher after the fourth island.
How many gems the game gives as compensation after an update.
Who gets it: everyone without a group yet: B.
How to find your group: The rule is “+B” now: the same for everyone, a fixed amount.
Whether the old music plays on islands.
Who gets it: new players only: A or B — equally.
How to find your group: If your island music differs from a friend's, you're in different groups.

Whether the game lowers graphics quality automatically. Only in the built-in config; the group is picked before the game starts.

A test of the ad delay from game start. It's empty now and affects nothing.
Switches to the old income-per-minute algorithm. The remote config has no assignment rule.
