Orderbook Test
A timed arbitrage test: each puzzle deals a few cards, single assets and baskets, each with buy and sell prices. Find a combination of trades that locks in a profit, then move to the next puzzle.
Realistic test mode
SaveYou will face 6 puzzles on one 3-minute clock. Each puzzle deals a few cards: single assets and baskets of them, each with a sell price and a buy price. Tap prices to build a position, and submit when your buys cover your sells at a profit. A wrong submission costs time, not points, and difficulty is mixed rather than ramping. The test opens with a short tutorial.
You score 1 point for each puzzle you solve with a valid arbitrage, and 0 for a skipped or unsolved one. Any correct arbitrage counts: find the simple one and move on.
