Blitz Tactics - free and open-source tactics trainer

Hi, I'm open sourcing a tactics trainer I shared on lichess forum a few months ago.

This is the website:
http://blitztactics.com

And here's the source code:
github.com/linrock/blitz-tactics

I haven't been as inspired to work on this lately, so I never got around to cleaning up the code. But I hope it helps with ideas for anyone building chess apps, as there are a lot of possibilities yet to explore for making chess more fun to learn.

Thanks for all your feedback and support - I still have a backlog of tasks to work through, and I'd started working on a puzzle editor. Not sure when I'll have a first version of that ready.

Until then, good luck and have fun!

Perfect! perfect! Wombo combo! perfect!
me: f*** yeah
try again (from the start)
me: f*** you :)

Very cool idea!!

Great respect for your work. Went through all 65 levels. Got a huge pleasure and benefit. Ideas and positions are very important for practical games. This is very important. I want to insert your analysis of the decision levels. 3-4 seconds for tactics too little. In my opinion it is bullet tactics. If the tooltip to appear after 10 seconds it would be a blitz tactic. The result trains the ability to skillfully work with the mouse. It is in my opinion wrong. IMHO. But the benefits so big. When will the new levels? I look forward and wish you success! PS: Can make difficult levels by 30-50 positions? To them were just harder to remember. Success to you and your beautiful idea!!

If it is based on rapid chess, then there are at least two common time controls.

3 minutes, plus 2 seconds per move.
Then : 180 seconds / 40 moves = 4.5 seconds per move plus a 2 seconds extra for every extra move in the puzzle.

5 minutes / 40 moves = 7.5 seconds per move.

I believe a fast blitz speed is three minutes with two seconds of increment time, but a blitz is also a 5 minute game. Why not create two time control sections. One would train players in the fixed 5 minutes, while the other section would train people in the increment timed puzzles.
