Crate Caravan

Ship exact contracts tier3, then4, then5. Select a column to stack the next delivery or ship its exposed top crate. Only tier3+ ships. A wrong contract tier still earns that many coins but does not advance the contract. Equal top crates combine repeatedly; there is no automatic horizontal merge.

The repeating delivery deck starts1,1,2. Bought cards insert NEXT and repeat on later circuits; capacity6. Small tier1 cards cost2, heavy tier2 cards start at4 and each heavy purchase raises its next price by2. Each completed circuit requires2 coins before the next delivery. Keep money for the return trip, or ship a crate to fund it. There are32 deliveries.

Tower load is the SUM of its tier numbers, not its crate count. Every tower must stay within3 load of its stronger adjacent neighbour; an empty neighbour contributes0. Check all five load readings and previews. Shipping a supporting tower can also topple its neighbour, so unload deliberately. The preview warns before a stack or shipment ends the run. Small cards can make useful braces. Retry repeats the fixed deck-building puzzle.
