The Piggy Bank feature was introduced in version 2.4 and offers a way to purchase gems at a discounted rate. When filled completely, a Piggy Bank will offer 3.5× more gems than standard gem shop prices.
How It Works
Players collect coins by playing the game. Once a Piggy Bank is full, it can be opened by purchasing it with real money. There are six tiers of Piggy Banks, each unlocked by opening the previous tier.
Piggy Bank Tiers
| Level | Coins Needed | Gems | Price (USD) | Gems per Dollar | Shop Gems per Dollar (Standard) |
|---|---|---|---|---|---|
| Plastic | 40 | 1,650 | $3 | 550 | 160 (or 320 for $2) |
| Bronze | 40 | 3,500 | $5 | 700 | 200 (1,000 for $5) |
| Silver | 50 | 8,500 | $10 | 850 | 240 (2,400 for $10) |
| Gold | 50 | 17,500 | $20 | 875 | 250 (5,000 for $20) |
| Platinum | 60 | 45,000 | $50 | 900 | 260 (13,000 for $50) |
| Diamond | 60 | 100,000 | $100 | 1000 | 280 (28,000 for $100) |
Note: Opening a Piggy Bank unlocks the next level. You must progress sequentially through each tier.
Effective Value Compared to 3× Gem Sales
Since you must spend on the less attractive lower tiers before you can get to the higher tiers, the difference between the 3.5x Piggy Bank and 3x sale isn’t as big as you might expect. The gem piggy is only a better value if you unlock at least the Silver Piggy Bank.
| Highest Unlocked Tier | Total Gems | Total Cost (USD) | Effective Gems per Dollar | Comparable 3× Sale Value |
|---|---|---|---|---|
| Plastic | 1,650 | $3 | 550 | 600 (1,000 ×3 for $5) |
| Bronze | 5,150 | $8 | 644 | 720 (2,400 ×3 for $10) |
| Silver | 13,650 | $18 | 758 | 750 (5,000 ×3 for $20) |
| Gold | 31,150 | $38 | 820 | 780 (13,000 ×3 for $50) |
| Platinum | 76,150 | $88 | 865 | 840 (28,000 ×3 for $100) |
| Diamond | 176,150 | $188 | 937 | N/A |
Tips & Warnings
- Prices shown are in USD and may vary by region. All prices are rounded to the nearest dollar.
- You can open a Piggy Bank before it is full, but you’ll reduce the value significantly. If you are playing often enough to want to buy gems, you shouldn’t have a problem filling up the piggies.
- The gem piggy is only a better value than the 3x sale if you unlock at least the Silver Piggy Bank.
