Gacha machine with commands

Updated: 30 October 2026

1. Setup (once)

/scoreboard objectives add coins dummy
/scoreboard objectives add roll dummy

2. Layout

An impulse command block with a button, set to Needs Redstone, followed by chain blocks set to Unconditional and Always Active. Put steps 3 to 6 in order.

3. Check emeralds

/execute as @p store result score @s coins run clear @s emerald 0
/execute as @p if entity @s[scores={coins=10..}] run tag @s add gacha
/execute as @p unless entity @s[tag=gacha] run tellraw @s {"text":"You need 10 emeralds","color":"red"}
/clear @a[tag=gacha] emerald 10

clear @s emerald 0 counts emeralds without removing any. Pick the player with as @p first, then test them, so a different player with emeralds is not chosen.

4. Roll 1 to 100

/execute as @a[tag=gacha] store result score @s roll run random value 1..100

See random command.

5. Prizes by range

/give @a[tag=gacha,scores={roll=1..5}] diamond 3
/give @a[tag=gacha,scores={roll=6..30}] iron_ingot 5
/give @a[tag=gacha,scores={roll=31..100}] bread 3

That is 5% jackpot, 25% win and 70% common. Change the ranges to change the odds, without gaps or overlaps.

6. Jackpot message and cleanup

/execute as @a[tag=gacha,scores={roll=1..5}] run tellraw @a [{"selector":"@s"},{"text":" hit the jackpot!","color":"gold"}]
/execute as @a[tag=gacha,scores={roll=1..5}] at @s run playsound minecraft:ui.toast.challenge_complete master @s
/tag @a[tag=gacha] remove gacha

Troubleshooting

• Says not enough emeralds: check the coins objective and that chains are Always Active.
• No prize: random needs 1.20.2 or newer.
• Bedrock Edition: use scoreboard players random @p roll 1 100.
