I have never tried using games such as the ones you've listed. The only games I've ever used in my classroom are the ones on icivics.org and Oregon Trail the one year I taught US History. Source: almost 2 years ago

This is basically how electronic voting systems like Helios work [https://vote.heliosvoting.org/]. They use additively homomorphic encryption to produce a tally for an election. Obviously a lot more stuff needs to be added to make this fully secure as an e-voting system [e.g. Zero-Knowledge proofs need to be added to the votes to ensure someone votes for a valid candidate, the decryption functionality needs to...

It's a beautiful piece of theory, but when the IACR tried to build a voting scheme based on that to elect their board annually (https://vote.heliosvoting.org/), they got caught by a non-obvious bear trap when you make the whole thing non-interactive (which is the way this is mostly used in practice).

There are a few good open systems used in production today, https://vote.heliosvoting.org/ is one. That said, there has been a huge amount of relevant cryptography research lately, particularly in the zero knowledge space, which unlocks more coverage of desirable security properties (less trusting of centralized providers, more privacy, more auditability, more deniability, etc).

While not built for the purpose of voting, there have occasionally been some coin-weighted polls using the Zcash blockchain. The ability to post encrypted and immutable transactions, and selectively share viewing keys has interesting possibilities, certainly. That said, we in the Zcash community have usually used another system when holding secret-ballot votes within our community: Helios [1] [1]... - Source: Hacker News / about 2 years ago
