0x20: MOV R3, R5 ; R5 now holds target 10 Now we need R0 to equal R5 after cycle 12.

Introduction: What is TOD-RLA? If you've stumbled upon the term "TOD-RLA," you're likely deep inside a niche puzzle environment—perhaps an online judge like CodingGame , a MIT Mystery Hunt side quest, or a reverse-engineering lab. TOD stands for Turn of Destiny , while RLA refers to Random Language Assembly (or sometimes Register Logic Array ). tod rla walkthrough

So we must fill 12 cycles with operations that keep R0 = R3 at the cycle, despite random swaps or skips. Step 2.3 – Handling Destiny Swaps Destiny swaps exchange R2 and R3 every 4 cycles (if the random square condition is met). That means R3 might unexpectedly change.

We need to design a loop that to the target regardless of skips. 0x20: MOV R3, R5 ; R5 now holds

Let's simulate worst-case scenario:

Solution: – instructions that produce the same result if repeated or skipped. TOD stands for Turn of Destiny , while

But R0 might be modified by random operations? No – only we modify R0. Destiny events never touch R0 directly. Good. Every 4th cycle, if PRNG yields a prime number, the instruction at that cycle is skipped. That means our carefully planned increment might be omitted.
