Super Satoshi Bros

Super Satoshi Bros is a version of the classic NES game which replaces all the original coins with new coins representing transaction outputs of the Bitcoin blockchain, in a way that nearly all transactions can be represented. The game begins in a random world corresponding to a recent block, one of the last 10,000. From here, the game continues in reverse direction, towards the original genesis block.

For example, the map for each block is given by:

            Satoshi.classicMaps[(block.block_no - 1) % 31]

And the relation between the new coins and Bitcoin transactions is given by this method in satoshi/satoshi.js:

            // Adds coins to map area for a given block
            Satoshi.addCoinsForBlock = function(area, block) {
              for (var i = 0; i < block.txs.length && i < 1000; i++) {
                var tx = block.txs[i];
                var d = Math.log(Satoshi.getValue(tx));
                var x = i * 10;
                var y = Math.min(10, tx.inputs.length) * 4 + 6;
                var w = Math.min(10, tx.outputs.length);
                var h = Math.min(10, d);
                Satoshi.addCoins(area, x, y, w, h, d);

So this means that a transaction's output value roughly corresponds to both the height and density of each batch of coins onscreen, while the width increases with the number of transaction outputs. This explains the large group of coins at the very start of each level, representing the coinbase transaction for the world corresponding to the current block.

Similarly, the transactions are evenly spaced horizontally throughout the level, but their vertical position increases with the number of transaction inputs -- so these might be valuable, but also become harder to reach.

The project is a minor fork of the FullScreenMario-JSON project, and would not be possible without either it or the original game.
FullScreenMario is a free HTML5 remake of Nintendo's original Super Mario Bros. It includes the original 32 levels, a random map generator, a level editor, and over a dozen custom mods. You may download the game for yourself from GitHub, the location of Full Screen Mario's open source project. Be sure to get the latest news on our Facebook and Twitter too!
FullScreenMario was made possible first and foremost by Nintendo, who originally created Mario and has since maintained the series. It would also not have been possible without the dedicated efforts of the Mario fan community over the past three decades, in particular
