Mempool Space Invaders is a free-to-play web game where players engage with real Bitcoin transactions by shooting down Bitcoin ‘whales’, which represent actual transactions on the Bitcoin network. Successfully destroying these whales adds their Bitcoin amount to the player’s score. Additionally, there is a unique bounty system in place where the first player to destroy a total of 10,000 BTC in the game will receive a reward of 10,000 satoshis, equivalent to approximately $7.30.
Mempool Space Invaders presents gameplay in which players shoot down Bitcoin ‘whales’ that represent real transactions on the Bitcoin network. When a player destroys a whale, the Bitcoin amount tied to that transaction is added to the player’s in-game score. The whales in the game correspond to actual transactions visible in the mempool or on-chain, and their BTC values determine the points awarded. Gameplay therefore links in-game scoring directly to real Bitcoin transaction amounts.
Failing to destroy a whale causes the player’s shields to deteriorate, reducing survivability within the round. After shield deterioration or other failure conditions, players have two options to continue: restart the round for free, or pay a continuation fee of 1,000 satoshis to keep playing the same round. The 1,000 sats payment option allows players to resume without losing the current session’s progress. These mechanics create a trade-off between restarting at no cost and spending a small fee to maintain momentum in a round.
The game’s developer suggested two approaches for players attempting to reach the milestone of destroying 10,000 BTC in-game. One approach is to broadcast a single large transaction of 10,000 BTC to oneself and wait for that transaction to appear as a whale in the game. The alternative approach is to broadcast two separate transactions of 5,000 BTC each, which the developer noted could avoid risking a single extremely large sum. The developer also noted that destroying 10,000 BTC in the game would correspond to roughly $730 million in real Bitcoin transactions. These approaches were presented by the pseudonymous developer as ways to generate whales large enough to be counted toward the 10,000 BTC target.
In Mempool Space Invaders, a notable feature is the bounty offered by the game’s pseudonymous developer, Jasonb. The first player to successfully destroy a total of 10,000 BTC in the game will earn a bounty of 10,000 satoshis, which is approximately $7.30. This bounty highlights the unique gameplay aspect of engaging with real Bitcoin transactions.
To achieve this target, Jasonb suggested players could either make a single large transaction of 10,000 BTC to themselves, or use two separate transactions of 5,000 BTC each. This dual-option approach aims to mitigate the risk of involving such a large sum in a single transaction.
The developer emphasized the importance of timing, warning players, “Just make sure not to spend too much in fees, or you’ll eat up all your winnings.”
It is also advised that these transactions be broadcast close together to ensure both can be targeted in the same game session.
Some players reported destroying 70 BTC in about 20 minutes. Other players reported destroying 30 BTC in about 20 minutes. These player comments indicate the amounts that individual players have reported achieving during gameplay.
The game’s bounty, offered by the pseudonymous developer Jasonb, awards 10,000 satoshis to the first player who destroys a cumulative 10,000 BTC in the game. The developer framed this target and bounty in discussion of how to generate large in-game whales. Destroying 10,000 BTC in the game would correspond to roughly $730 million in real Bitcoin transactions.

Mempool Space Invaders is an innovative web game that creatively integrates real Bitcoin transactions into its gameplay. By allowing players to interact with Bitcoin ‘whales’, the game provides a unique intersection of blockchain technology and gaming. The enticing bounty of 10,000 satoshis for destroying 10,000 BTC further enhances player motivation, blending real-world financial stakes with engaging, interactive mechanisms. This inventive approach offers an exciting experience for players and highlights the potential of integrating real-world data into the gaming environment.
