Sword Enhance (Sword Upgrade Game)

How to play

You start a run with 800 gold and a rusty +0 sword. Press Enhance to pay for a strike at the anvil: if it succeeds, the sword goes up one level; if it fails, it may break. Before every strike the game shows the exact success chance, the price of the strike and what the sword would sell for. The chance starts at 95% and drops as the sword climbs, while the price rises. From +0 to +4 you are in the safe zone, where a failure only costs gold. From +5 upwards a failure shatters the sword and you start over with a fresh +0. Press Sell to trade the sword for gold: its value grows steeply with every level, so a +8 pays for many more tries, and you get a new +0 to work on. The sword changes as it grows, from rusty iron to steel, azure, arcane, golden and crimson blades, up to the Legendary Sword at +20. The run ends when you forge a +20, when you run out of gold with nothing worth selling, or when you press End run. Your score is the highest level your sword reached during the run.

Tips

• +0 to +4 is the safe zone: failures cost gold but never the sword, so climb through it freely.
• A +8 to +10 sword sells for enough gold to pay for dozens of tries. Cash in before your wallet runs dry.
• Your score is your peak, not your gold. A sword you sell still counts for the level it reached.
• Even 85% means one break in about seven strikes. Read the odds before every press.
• Swords from +12 up are worth a fortune, and losing one hurts. Decide before the strike whether you are farming gold or chasing a record.
• The final strike from +19 to +20 succeeds only 15% of the time. That's why the Legendary Sword is so rare.
