Decipher EVM puzzles are basically a collection of EVM opcodes puzzles that includes a bunch of different opcodes which can be executed successfully only if you provide the right inputs.
The Decipher EVM Puzzle game is an extended version of Franco's EVM puzzles but with additional complexity, a difficulty-level selector making it available not just for senior devs but also beginners, and more interesting puzzles covering a wide range of opcodes.
Every puzzle might require one of the following as input from the player:
- CallData only
- CallValue only
- Both CallData & CallValue
Your main goal as a player is to provide the right set of inputs so that the transaction doesn't get reverted.
If it reverts, you FAIL...❌ If it executes successfully, You SOLVED that particular puzzle. ✅
- Solutions to puzzles can have more a formulae instead of one specific value.
- For instance, some puzzles may require a type of input where Calldata size must be n and CallValue must be n+4,in order for you to solve it correctly.
- For such cases, correct CallData Size can be 4 or 5 or 6 and CallValue can be 8 or 9 or 10 respectively
- It's imperative to understand the formulae rather than chasing 1 specific calldata size or callvalue as the right answer, for such a puzzle
- Solutions to the same puzzle can also be more than 1 specific input.
