Well, it depends on what your rabbit likes to play with. Since you only just got them, it might take you some time to figure out what their favorite toys or games are.
One of ours likes to dig, so we gave her some towels and rags that we stuffed in between the sections of the sofa, and then she'll dig them out and wait till we stuff them back, and dig again, and so on. She also likes to play with cardboard, so we have some pieces of cardboard that I build into a house or something for her, and she'll come over and pull it down and then "help" me move the pieces of cardboard around, or throw them around. When she was young she liked to go on "horsy" rides on our shoulders
I'll try to insert a picture of that.
Our other bun likes to play with balls or other toys she can grab and throw, so she'll take a ball we offer and pull it away and toss it, sometimes we throw it at her and she runs after it and throws it aswell. She also likes to shred paper, so she'll take a newspaper or something we hold and play "tug'o'war" with it and pull it out of our hands.
Just try some different things to start with, and see what they react to and like. There are several websites that have suggestions for toys, the House Rabbit Society is one of them.
Have fun playing with your bunnies
