Tactics Hack 2.0 + Redeem Codes

Access to web apps is spotty. They’re useful, when they work, but the videos still are completely broken, for example. Also it’s entirely too easy to tap a button that takes you to a place from which you cannot return. There’s a lot of potential for this app in the Chessbase ecosystem, but Chessbase itself seems completely uninterested in it these days. CT-ART is a far better tactics trainer than this is. This *could* be a great app, if CB ever decides to care about it. Until it does, there’s no real point in buying it.

This doesn't feel like an iOS game at all. The interface is horrible.
The chess problem may be interesting but they are badly designed and poorly described: I tried two and they were both 'Black to move and win', except it didn't meant in the next move! And White's response to the "hinted" move is not forced... so badly posed chess problems.
In short... a poorly done chess problems app.

Why is this a Featured App???

Not sure what they're thinking putting this on such a respected brand. Input is clunky and it sometimes takes several tries for a move to register. Some of the variations seem a bit odd too. It may have just been the frustration building up, but it seemed to ask you to perform menial tasks such as find the pin when there was a mate on the board.

Tactics are a decent training tool IF you can go back and figure out why something was played. Otherwise it is an exercise in futility. A tactics trainer should let you play around with the solution so you understand what just happened. This doesn't include that, it doesn't give variations when you've solved the problem, and you can't even stop and look at the board when you've found the solution. It just takes you to the next task without giving you time to learn from the puzzle.

The result is a waste of time.

Unfortunately, the updated app still crashes every time I reach a specific endgame tactic in which each side has 3 pawns and no pieces. Once I reach this problem, it will crash every time I make a move. If I try to skip this problem, it will crash on the next problem, every time.

This is the most confusing, least functional chess tactics program I've ever seen for iOS; there's no reason in the world this software should've been released in this lousy condition. It's embarrassing how badly ChessBase is adapting to the new world of tablet computing and mobile apps.

First a "tactic" in this app is 1 MOVE, so 1 "puzzle" could count for as many as 5 "tactics" so you may not get 100 puzzles for 99¢, second, not all are tactics, some puzzles are just for the best move, which can be confusing if you're looking for a tactic.

There are no instructions on how to use this app.

At a certain point the app will crash EVERYTIME you key in a move.
