# Capacity and Fee

Once the tournament opens, it will be Open for Registration. Players must send their Fusions to the arena venue together, along with the registration fee. At this point, the Fusions will remain in the arena until players choose to leave. When players decide to leave the tournament that has not yet begun, they will have the option to choose whether they want to return their Fusions to their wallet, or leave their Fusions in the arena venue for the next registration, avoiding the transfer GAS fee.

| Arena Capacity | Registration Fee |
| -------------- | ---------------- |
| 128            | .75 GAS          |
| 64             | 1.5 GAS          |
| 32             | 2.5 GAS          |
| 16             | 3.5 GAS          |
| 8              | 5 GAS            |
