I had the same question before I started playing Sweet Bonanza, and I found exactly what you’re looking for. You can try the demo version for free at https://sweetbonanzas.com/ This lets you experience the game risk-free, using virtual rubles to get a feel for how the game works. Plus, the website offers a detailed review and guides on strategies, so you’ll know what you’re doing when you’re ready to play for real money. It’s safe, and it’s helped me understand the game without any pressure. Highly recommend giving it a go if you want to test the waters first!
