Drag a piece onto the grid and the infection spreads from its arms. Rays run to the edge, diagonals run corner to corner, a blot takes the eight cells around it. Walls block the spread, repel switches push it back, reset traps wipe the board. Infect every cell to solve the level.
It ships with the 128 classic levels from the 2014 original, 16 generated worlds holding 346 generated levels of graded puzzles, a daily board that is the same for everyone, and an endless mode by grade. A ten-step tutorial is offered the first time you open it and stays available from the menu. Fourteen languages. No accounts, no sign-in, nothing to set up.
For bugs, questions, refund problems, privacy requests or anything else: bloodhoundstudios@gmail.com. It is one developer answering, so allow a few days.
When reporting a bug, the build number helps. It is on the Settings screen at the bottom.
I bought "remove ads" and it is gone. The purchase is attached to the Google Play or Apple App Store account that bought it. Sign in with that account on the device and reopen the app; it reads the store's purchase record on launch and drops the ad gate. If it still does not appear, email the address above.
I want a refund. Refunds are handled by the store, not by Bloodhound Studios. Use the refund process in Google Play or the App Store.
I want to change my ad consent choices. Open Settings ▸ Privacy options inside the app.
I want to erase my progress. Settings ▸ Reset progress, then tap again to confirm. Uninstalling the app also removes everything; nothing is stored off your device.
