# Join IDO

## Key Rule

#### 1. Guaranteed Round:

* Guaranteed RoundBSCS has implemented the **“Min - Max Allocation Range Selection"** feature for IDOs on our platform available for the **“Guaranteed Pool".** The Allocation Range will be based on the **BSCS** [**Tier System**](/defi-1/tier-system-and-allocation.md)**.** 
* The **Min-Max Allocation Range** will be calculated 24 hours before the Pools Start

#### 2. First Come First Serve Round:

* The **remaining allocation** from Round 1 will be split evenly into a fixed Ticket number with equal allocation.
* The Ticket can be purchased in the FCFS rule.
