The new closing date for the 17. ECSC (https://www.ecsc2024.de) to be held at Hagen, Germany at April 19-21, 2024 is
March 15, 2024.
Entry fee is 60 EUR for registration and payment received until March 15, 75 EUR later (limited availability). For registration the Open Solving tourney only the fee is 20 EUR.
One more change: The Open solving on Friday (April 19) will start two hours later, at 17:00 and run until 20:30. This seems to be more convenient for solvers travelling on Friday.
