Splinterlands/Steemmonsters started life on the Steem blockchain and the game still runs on the Steem blockchain. Recently, the team branched out into the TRON community and ran a successful SEED campaign where you could purchase cards using either TRX or SEED tokens.
This resulted in the creation of BETA tokens, PROMO tokens and DEC tokens that can be traded against TRX. The nicest TRON market for me is the TRONWATCH Market:
Using the TRONLink browser extension, you can easily send and receive tokens and trade them against TRX. These tokens can then be redeemed through the Splinterlands website and sent to the Steem-Engine.com Market where DEC and BETA tokens can be traded against Steem.
If you are trade savvy, then you can identify times when purchasing DEC or BETA tokens on the TRON Market and selling them through Steem-Engine can be profitable.
This is a great community that has connected TRON with Steem through Splinterlands and Steem-Engine.
