The Bird is the Wild symbol in the game, paying 5000x the line bet for 5 of them, and substitutes for other symbols except the Scatter and the Bonus symbols. Sadly, the Wild is a dumb symbol, for not doubling any wins with it, and not becoming stacked or expanded. The Wooden Gate is the Scatter symbol, it doesn't pay anything for itself, but getting 3, 4 or 5 of them awards 20, 30 or 50 free spins with all wins doubled. More free spins can be retriggered. The Key is the Bonus symbol, it doesn't pay anything for itself too, but getting 3 or more of them awards Explore the Secret Garden Bonus game. Gees! Only now I realise that this game uses 3 dumb symbols - the Wild, the Scatter and the Bonus symbols, greatly reducing a lot of additional wins by getting them. As for the other symbols, the Roses pay 500x, the Girl pays 400x, the Squirrel pays 350x, the Boy pays 300x, and the rest pay from 150x to 65x, all per line bet for 5 of each kind, making the paytable a low one.
I like playing Explore the Secret Garden Bonus game, whereby you water the plant bed and collect roses for coins, a watering can and a key, to proceed to the next level. The game ends when you don't get any key to open the next gate. The maximum win is 5000 coins, or 250x the total bet amount, which is much better than what most other Bonus games can pay. The Free Spins games can be lots of fun and enjoyable at the right time, with retriggers occurring now and then. My best win on this Secret Garden game was from a Free Spins game that gave a total of 120 free spins, with a nice big payout I can't remember how much, but it was definitely between 500x to 1000x my bet amount. This happened many years ago, before I even knew how to take screenshots! Hehehe.
