Given a reference text about Ingwelala, tell me which game farms are on the reserve.

Ingwelala is a private stakeholder nature reserve on the bank of the Nhlaralumi River[1] in the heart of the lowveld, about 65 km from the town of Hoedspruit. The reserve of some 3,000 hectares forms part of the Bushbuckridge Municipality, and adjoins the Umbabat Nature Reserve and the unfenced Kruger National Park.

Ingwelala includes the following game farms:

Argyle – 1,499 ha registered as Ingwelala Shareblock Ltd.
Buffelsbed – 1,018 ha registered as Buffelsbed Shareblock Ltd.
Goedehoop – 372 ha registered as Ingwelala Holdings Ltd.
Si Bon – 257 ha registered as Si Bon Property Holdings Ltd

Argyle, Buffelsbed, Goedehoop, and Si Bon are the game farms on Ingwelala.
