It is possible to block by tapping your car and tapping the owner's card but the drag and drop functionality that is in the instructions in the tutorial just simply does not work and it took me awhile to figure out how to work around this but there is a workaround. For the time being on Android devices you should change the tutorial to construct the user to tap your card in the account of that function does work. It makes sense to me that this wouldn't be easy for users to figure out cuz it took me the good five or seven minutes to figure out how to work around it given that the instructions were unclear and incorrect.

This was reported back in 2021. It's 2024 and I'm having this same issue. How is it possible for a bug to STILL be present? if a game-killing bug shows up in the tutorial and has been around for this long, I can't imagine how bad the rest fo the game must be.

I have an iPhone X and have also the same issue

You have to first tap your 2/2 blocker and then tap the opposite creature and it should show you the option to push forward

I am having the same issue, in the first match of the tutorial. iPad 9th Gen iOS 16.2

I am on an iPad Air 2 and cannot block in 3/2023.

Same here on Android

I’m on an iPhone - also can’t block. Game is unplayable.

Same issue. Can't block during tutorial. Won't let me drag blocker and only gives 'No Blocks' button option but tutorial guide won't allow that either since that would cause a loss. Only option is to concede...and Uninstall, since this has apparently been an issue for 9+ months. Disappointing

Same issue. Can't finish tutorial. Get 2turns in and I can't block.

Same issue

Android, when asked to block in tutorial I can only select cards but there is no button that says block like when you attack. It will not let me drag the blocking cards to attacking card either. There seems to no option to skip. Restarting the app didn't help nor did conceding match. Please fix this.

Android
I'm playing the tutorial, once I'm trying to block, I can't, blocking is not shown as an option, I can't drag my creatures, I can't end the tutorial, so the game is unplayable.
