How to play
Faktore Build the product
You have a board of digits and three products to make. Chain neighbouring digits, diagonals included, and multiply them: if the result is one of the products, the move counts. The whole calculation is shown while you build it. Each move in a row raises the combo, and the combo is your multiplier.
Bide Choose the path
You start at the entrance with a value and climb through a network of multipliers. Each node shows the result you would get, so there is nothing to calculate: your job is to decide. If a node overshoots the target, or the target can no longer be reached from it, it goes dark. Nodes you step on are used up, and the round lasts as long as the network does.
In both games
- Each game has nine rounds, with a boss in the third, sixth and ninth. Each boss changes a rule.
- Between rounds, in Upgrades, you buy relics with the coins you earn during the game. Relics are lost when the game ends and never cost real money.
- Each game has its own tutorial, which you can replay from “How to play”.
Frequently asked questions
I have lost my game
Each game keeps one game per difficulty (and in Bide, per mode too), exactly where you left it. If you start a new game on that same difficulty, the previous one is replaced. Check that you are looking at the right game, difficulty and mode.
I changed phones and my progress is missing
On the same kind of phone, progress usually comes back on its own when you reinstall, because Android and iOS back up app data if you have that feature turned on. That system backup does not move from Android to iPhone or the other way round. We are preparing Biderka's own backup, which will; we will announce it here when it is available.
I paid and still do not have Biderka Complete
Go to Settings, open “Biderka Complete” and tap “Restore purchase”. Make sure you are using the same Apple or Google account you bought with. If it still does not appear, write to us saying which store you bought from and we will sort it out.
What is free and what does Biderka Complete include?
For free you can play the tutorial and the first three rounds on Easy in each game, boss included, and always see your statistics. Biderka Complete, a one-time payment, opens all nine rounds and all four difficulties in both games, plus the weekly challenges.
I have Biderka Complete and a difficulty is still locked
That is expected: each difficulty opens when you win the previous one. Win a game on Easy to open Medium, and so on.
Are there ads or a subscription?
No, and there never will be. No ads, no subscription, no lives that run out, and nothing you pay for to win.
The game makes no sound or does not vibrate
In Settings, under “Audio and vibration”, check the sound effects and vibration switches, make sure the phone is not on silent, and that the media volume is up.
Can I play offline?
Yes. Biderka works fully without an internet connection.
Which languages is it in?
English and Spanish. The game follows your phone's language, and you can change it by hand in Settings.
Reporting a bug
If something behaves oddly, tell us. It helps enormously to know:
- Which phone you have and which version of Android or iOS.
- The Biderka version, shown in Settings under “About”.
- Which game, difficulty and round you were in.
- What you expected to happen and what happened.
- A screenshot, if you can.
