Actually remember what you studied.
Free keeps the habit alive. Plus is what makes it stick — every game you miss comes back on a schedule built around when you forget, not when you happen to feel like studying.
One plan. That's the whole menu.
Plus is everything. Only add a Boards Sprint below if you're sitting a specific exam and want its question bank or simulator.

Plus is what keeps this running
I'm an optometrist and I build OptoConnections on my own — the questions, the cases, the code. There's no investor behind it and no ads on it. Subscriptions pay for the servers and buy the hours that become the next game, the next batch of cases, the next tool.
The daily games stay free either way. If this has made your studying easier, Plus is how you keep it getting better — for you and for whoever's a year behind you.
