1. The round counter tracks the continuing session

- Escalate the threat predictably and let players preserve their result.

- [Bloons TD 6](https://store.steampowered.com/app/960090/)

## How it works

The player survives successive waves and decides whether the extra reward is worth the next stage’s risk.

## Variants

### Action → reward

<a id="endless-waves-loop"></a>

- Survive the assault longer → reach further reward thresholds. <a id="endless-waves-repeat"></a>
- Choose a reward or upgrade between waves. <a id="endless-waves-option-2"></a>
- Stop a run at a convenient threshold. <a id="endless-waves-option-3"></a>

## Design example

After every fifth wave, the party can claim its loot or stay for the next chest.

## 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.
