## How it works

The system awards bounded progress during absence, with explicit simulation rules and caps.

## Variants

### Variants

<a id="offline-accumulation-options"></a>

- Accumulate resources up to a defined cap. <a id="offline-accumulation-option-1"></a>
- Choose an active task before leaving. <a id="offline-accumulation-option-2"></a>
- Improve offline production speed or capacity. <a id="offline-accumulation-option-3"></a>

## Design example

On returning, the player receives ore from several hours of mine operation.

## 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.
