The Block Doubler is an upgrade that increases the number of Blocks the player earns when breaking a Block Wall by 1 per upgrade. Up to 4 upgrades can be purchased, and they cost $2.99(1.0) / 300 Runic(2.0) each. In Version 3.0, it was replaced by the Block Fortune Skill in the Player Skill Tree. Upon updating to Version 3.0, any Block Doubler upgrades the player had purchased are applied to the Legacy Relic.
