## How it works

Progress comes from price differences after fees, demand, risk and tied-up capital.

## Variants

### Variants

<a id="market-arbitrage-options"></a>

- Buy underpriced listings and resell. <a id="market-arbitrage-option-1"></a>
- Use price differences between markets. <a id="market-arbitrage-option-2"></a>
- Hold stock until demand changes. <a id="market-arbitrage-option-3"></a>

## Design example

A trader buys cheap reagents and sells them where a potion order has raised demand.

## Context and limits

A systematic RPG grind reference: 110 mechanics and 330 variants in 18 sections. Four layers answer different questions: what the player repeats, what develops, how rewards arrive and what constrains the loop. It covers single-player RPGs, ARPGs, MMORPGs and adjacent management and accumulation systems. Every mechanic has an explanation, variants and a hypothetical example; coverage, combinations and verified game observations follow the catalog.
