Stock up before a level: from level 10 a Ready card shows the level's colours, its time and block count, and your boosters to top up. Short of coins at the last second? The Out of Time, revive, lives and booster popups offer the coin pack that covers the gap. Pip's piggy bank fills with every first win on the map. Open it from 500 coins. Style shop: pickaxes, capes and avatar rings for coins. Your first purchase pays double coins, and one coin pack a day pays 50% more. Optimized for iPhone Duo: the game fills the unfolded screen and follows a fold or a turn mid-game.

Optimized for iPhone Duo: Gem Jam fills the whole screen, open or folded. New Graphics setting (Settings and Pause): Automatic picks the right level for your phone, or choose High, Medium or Low. Smoother on older devices. Gem Jam now also speaks Danish, Norwegian, Finnish, German and French.
